Lot	Photo	Description	Realized
Lot 1458		2.6 Inch Pre-Maxilary T-Rex Tooth. Virtually all T-Rex teeth found are shed teeth that broke off while the T-Rex was feeding on another dinosaur. Usually these teeth are just fragments or are broken into many pieces, but this extremely large 2.6 inch Pre-Maxilary tooth is the exception. Only the tip was found separated from the rest of the tooth and put back into place, otherwise there is no restoration. There is some wear to the enamel at the tip that occurred while the T-Rex was still alive and there are some light cracks in the enamel that are always present. Pre-Maxilary teeth were found at the front of the jaw and were larger as they were used to strip meat from the bone. They are very distinctive in having two rows of serrations on the opposite sides of the regular teeth. This 65 million year old treasure was found on a private ranch in the Hell Creek Formation of Montana and is displayed in a 5.5 x 4.5 inch Riker mount. Add $25.00 for domestic shipping. Estimated Value $3,000 - 4,000. View details and enlarged photo	Realized $2,645
Lot 1459		280 Million Year Old Amphibian and Two Fish. On the same 16 x 12 inch matrix is a 280 million year old remarkably well preserved early amphibian, Sclerocephalus hauseri as well as two primitive fish. The important early amphibian is over 11 inches long and nearly complete with a well detailed 1.75 inch wide arrow shaped skull with a lower jaw filled with tiny sharp teeth and detailed light and dark brown patterned skin impressions along the entire body. Only one of the four feet and a few small leg bones and digits are missing. The two primitive fish Paramblypterus sp. are 6 inches and 3.5 inches long and preserved with their skin and shark-like heterocercal fins. Skin impressions are rare and even the texture of the skin is detectable in these impressive fossils. Multiple species preserved together is extremely rare and scientifically important. These museum quality fossils come from the Odernheim Pfatz in Germany from a quarry that has been closed since 1984. Estimated Value $2,000 - 2,500. View details and enlarged photo	Unsold
Lot 1460		280 Million Year Old Amphibian Larvae. Even though the earliest amphibians ventured forth on land, they still deposited their eggs and the hatching larvae went through all of their developmental stages in the water. This set of four fossils represents four developmental stages from long thin tadpole like animals to a 2.5 inch long transitional animal with short tiny legs to a 3 inch long complete amphibian with small very defined legs but still possessing gills which are visible between the head and first legs. The exact species of amphibian cannot be determined from the larvae, but these fossils were found in the Pdernheim Pfatz in Germany and are found together with adult specimens of Actinodon and Sclerocephalus. All four of these fossils are displayed in a 9 x 6.5 inch clear plastic box. Add $25.00 for domestic shipping. Estimated Value $400 - 550. View details and enlarged photo	Realized $334
Lot 1461		280 Million Year Old Amphibian With Skin. All fossils of the first amphibians are rare and found in only a few locations in the world. Amphibian fossils that still preserve their skin structure are even rarer. The best preserved amphibians come from a site closed to collecting for over 20 years in the Odernheim Pfatz in Germany. This large 9.5 inch long amphibian, Actinodon on a 17 x 11 matrix is nearly complete, missing only a few bones in all of the four limbs but possessing a large two inch skull with sharp pointed teeth as well as the all important skin impressions which show skin texture and patterns. Add $25.00 for domestic shipping. Estimated Value $1,000 - 1,400. View details and enlarged photo	Unsold
Lot 1462		American Indian Stone Knife Blade. Length 10 7/8in., width 3in., Wyoming Type Cody Knife Blade. Reportedly found near Kirby, WY in Washington County. Well carved with fine serrated edges. Housed in a clear museum type specimen box. A rare and choice quality American Indian relic. Estimated Value $400 - 600. Accompanied by a certificate from Relic Authenticators of America. View details and enlarged photo	Realized $483
Lot 1463		Bizarre Trilobite with Long Eye Stalks. Neoasaphus kowalewski was a very strange looking trilobite with extremely long one inch eyestalks and must have looked like something from another planet as it crossed the warm ocean floor 450 million years ago in the Wolchow river near St. Petersburg, Russia. This strange trilobite would bury itself in the sand with just its eyestalks exposed to hunt small prey animals and protect itself from predators. This lovely complete brown trilobite is 2.75 inches long on a 5.5 x 4.5 inch limestone matrix. The best preserved and most beautiful trilobites come from Russia and are stunning with the medium brown color contrasting the light tan matrix. Add $25 for domestic shipping. Estimated Value $550 - 700. View details and enlarged photo	Realized $460
Lot 1464		Dragonfly from Solnhofen. This 150 million year old dragonfly is beautifully preserved in the fine grain lithographic limestone matrix. The rare species Protolindenia wittei is one of the largest and most dramatic. Perfectly positioned on a 7.5 x 6.5 inch limestone matrix, this huge dragonfly has a 4 inch long body and each wing is 3 inches long. The head, antennae, three legs, body ending in two hooks, and amazing wing detail make this dragonfly one of the finest to be found from the famous lithographic limestone quarry of Solnhofen where the first bird fossils were found. Add $15 for domestic shipping. Estimated Value $800 - 900. View details and enlarged photo	Unsold
Lot 1465		Fossil Badlands Turtle With Bite Marks. Stylemys nebrascensis was a 30 million year old tortoise that roamed the White River Formation of the Badlands of South Dakota. This interesting specimen measures 7 x 6 inches and is well preserved with bite marks from some sharp toothed predator with three bite marks on the top of the shell and another bite mark on the plastron. The outer carapace was formed by a series of scutes made of keratin originally (the same material our fingernails are made of). Most of the underside of the tortoise, the plastron, which was formed by bony plates is preserved along with a 1.5 inch leg bone and other bones are clearly still buried in the matrix. Fossils that show evidence of predation and possibly what killed them are highly valued for their scientific interest as well as their beauty. Add $20 for domestic shipping. Estimated Value $400 - 600. View details and enlarged photo	Unsold
Lot 1466		Giant Complete Ammonite. Ammonites are extinct cephalopods that resembled an armored squid. Since their tentacles and body were soft tissue they do not fossilize and we only find their beautiful shells remaining. This giant 14 x 10 inch Cleoniceras ammonite is 110 million years old from the island of Madagascar and is complete with amazing hues of caramel to light brown on its polished outer surface. It is one of the most striking museum quality ammonites, with most of its surface covered with a fern shaped suture pattern which strengthened its calcium carbonate shell. Each species of ammonite could be identified just by its own distinctive suture pattern. This ammonite has both size and beauty. Add $30 for domestic shipping. Estimated Value $600 - 800. View details and enlarged photo	Unsold
Lot 1467		Golden Ammonites From Holzmaden, Germany. Holzmaden is famous for its yield of excellently preserved fossils that are roughly 180 million years old and especially for its ichthyosaurs and golden ammonites. These ammonites are extinct relatives of octopus and squid that have had their mother of pearl shell replaced with a golden colored pyrite over the millions of years that they were buried. On this immense 35 x 28 inch black shale matrix is a very large 8.5 inch in diameter pyritized ammonite Harpoceras sp. as well as over 20 other smaller Harpoceras and Dactylioceras ammonites. These ammonites show the defining ribbing patterns that indicate the size of the inner chambers. All ammonites from Holzmaden have been flattened under the pressure of fossilization and the plates can easily be mounted and hung on a wall if desired. Add $80.00 for domestic shipping. Estimated Value $750 - 1,000. View details and enlarged photo	Unsold
Lot 1468		Huge 210 Million Year Old Aquatic Reptile. Ichthyosaurs were a fast swimming marine reptile that have been extinct for more than 100 million years and somewhat resembled dolphins in shape. Their bodies were built for speed like a dolphin but their skeleton was very different. The earliest ichthyosaurs were much more reptile-like with longer thinner bodies and smaller fins and paddles. Mixosaurus panzianensis, found in the 210 million year old Guaning Formation of Panxian County, China, is one of the earliest and most primitive of ichthyosaurs. It had a long thin body with heavy vertebrae and a straight reptile-like tail. This 21.5 inch long specimen is more complete than most specimens even though the ribs and some of the leg bones are disarticulated, but its vertebrae, tail and parts of all four paddle bones are present. The large skull is 5 inches long with several sharp teeth still present and Mixosaurus had very large eyes which may indicate that it swam at great depths in search of prey. The 1 inch long paddles are just reptile feet with a few extra phalanges extending their length to create paddles for swimming and steering. This rare and important early ichthyosaur fossil is nicely centered on a 23 x 11.5 inch black stone matrix, backed for stability as the matrix is somewhat fragile and the recovered specimens always come out in a number of pieces. There is 10-15% restoration on some of the teeth, but overall the specimen is one of the finer fossils available of this rare primitive ichthyosaur. Add $75 for domestic shipping. Estimated Value $3,500 - 4,500. View details and enlarged photo	Unsold
Lot 1469		Ichthyosaur From Holzmaden, Germany. The 180 million year old Ichthyosaurs are the most famous and popular of the fossils found in the slate pits of Holzmaden, Germany. Of all the aquatic reptiles of their time, the dolphin-like Ichthyosaurs were the best adapted to their environment and were known to have live births. This large 31 inch long Stenpterygius quadriseissus Ichthyosaur is well articulated with the excellently defined 3-dimensional bones that Holzmaden is known for, missing only the snout on the head and two of the legs. There are some teeth visible as well as a sclerotic ring, which was a bony plate surrounding the eye giving it protection. The delicate rib bones, body and tail vertebrae, as well as two of the foot paddles are in excellent condition and the Ichthyosaur is nicely centered on the 33 x 19 inch natural stone matrix. Complete Ichthyosaurs from Holzmaden sell for more than $25,000. This remarkably well preserved specimen should be a bargain due to its missing snout. Add $85.00 for domestic shipping. Estimated Value $5,000 - 6,500. View details and enlarged photo	Unsold
Lot 1470		Merycoidon Mammal Skull With Leg And Hoof Bones. Merycoidon was a strange 30 million year old mammal from the extinct oreodont mammal group that has no modern relatives and had some features of a pig and some of a deer. This original limestone block is 14 x 10 inches and contains an 8 x 6 inch skull that has several cracks, but is nearly complete. It displays an excellent upper jaw with most of the teeth present on both sides with one nice incisor that is sharp and somewhat pig-like and one complete lower jaw with most teeth and the other side of the lower jaw still mostly buried in the matrix. In addition, there are several bones of one of the legs ending in two partial hooves and also several vertebrae from the neck. This is a completely original fossil block found on privately owned land in the White River Badlands formation of South Dakota. Add $50.00 for domestic shipping. Estimated Value $750 - 950. View details and enlarged photo	Unsold
Lot 1471		Mesosaurus Marine Reptile. Mesosaurus was a very important 260 million year old marine reptile that was the first known reptile to return to the sea shortly after evolving from amphibians. It helped prove the theory of continental drift as it is found only on the western part of South Africa and the eastern part of South America. This huge nearly complete 23 inch long fossil on a 21 x 10 inch limestone matrix is from the Irati Formation of Brazil. The attractive brown bone has excellent detail of the vertebrae, rib bones, delicate feet and crocodile-like skull with several small sharp teeth. This considerably above average specimen is missing only one leg and some bones on one of the other legs and a few bones at the tip of the tail. This fossil Mesosaurus has both size and quality as the average Mesosaurus is only 12-16 inches long and missing two or more legs. Add $35 for domestic shipping. Estimated Value $1,700 - 2,500. View details and enlarged photo	Unsold
Lot 1472		Oviraptor Dinosaur Egg. This huge 8.4 x 4 inch Oviraptor egg is much larger than eggs normally found in the Nanxiang Basin, Guandong Province of China. It is also much more complete, having more than 95% of the original shell intact. Though very slightly crushed, the egg still maintains its original shape and is a colorful reddish brown, reflecting the color of the stone where it was removed. As no more dinosaur eggs are coming out of China, this is an important opportunity to acquire a museum quality Ovirapter egg. Add $25 for domestic shipping. Estimated Value $800 - 1,200. View details and enlarged photo	Unsold
Lot 1473		Pair Of Unhatched Therizinosaur Eggs. Therizinosaur was a most bizarre and unusual looking dinosaur with some characteristics of a meat-eating dinosaur, such as walking bipedally and having large sharp claws, and some of a plant-eater, including a small head, long neck, and flat teeth. In addition, at least one species of Therizinosaur was feathered. This matched pair of unhatched eggs are each 4 x 3.75 inches and remain in their original 8.5 x 4 inch red stone matrix. The gray eggs maintain 50-70% of their original shell, which is layered under thin sections of stone matrix. Embryos have been found in a small percentage of this type of egg, but these specimens have not been x-rayed. Found in the Xixia Basin of the Henan Province of China, this specimen is estimated to be about 70-80 million years old. Add $25.00 for domestic shipping. Estimated Value $600 - 800. View details and enlarged photo	Unsold
Lot 1474		Petrified Jurassic Pine Cone. This exquisite 2.7 x 2.1 inch 160 million year old pine cone from Patagonia, Argentina has been cut in half and polished to reveal the inner beauty of the silicified seed kernels fossilized intact within. The inner core is a light brown and the seeds and outer areas range in several hues from tan to orange. The outer surface of the pine cone has been preserved with excellent detail. This rare preservation came from some giant Araucaria mirabilis pine trees that were buried under volcanic ash. There is great demand for these beautiful pine cones as the site has been closed to collectors. Add $15 for domestic shipping. Estimated Value $450 - 550. View details and enlarged photo	Realized $384
Lot 1475		Petrified Wood Sphere. This large 4 inch in diameter sphere is made up of 5-12 million year old fossilized Sequoia wood from Vantage, Washington. The white and various hues of brown clearly show the growth rings of the tree and in sphere form look like a mysterious planet in a galaxy far, far away. This large, rarely found, fossil sphere comes with its own custom swivel wooden stand and should appeal to fossil, mineral and sphere collectors. Add $15 for domestic shipping. Estimated Value $500 - 650. View details and enlarged photo	Unsold
Lot 1476		Plate of White and Gold Ferns. 300 million years ago when these ferns were fossilized in St. Clair, Pennsylvania, trees were much different than they are today with ferns and cycads dominating. These seed ferns became extinct around 73 million years ago. This huge 21 x 11 inch black shale slab is totally covered with dozens of white and gold ferns. These fronds fell into a bog where its oxygen depleted environment turned the leaves into pyrite and then they turned white from aluminum silicates or gold from the presence of iron ore. This plate is much larger than usually found and is both detailed and very colorful. Add $25.00 for domestic shipping. Estimated Value $400 - 500. View details and enlarged photo	Unsold
Lot 1477		Polished Petrified Wood Section. This exceptionally large 11 x 11 x 0.75 inch 225 million year old agatized and polished section of petrified wood is a complete section with bark along the outside. This section is from Madagascar, from the Araucaria tree (a conifer) also known as a monkey puzzle tree. Known as "rainbow wood" because of the wonderful mixture of reds, oranges, gold, browns and grays, these colorful sections are in great demand and are rare as most fossilized wood found in Madagascar just have tones of tan and brown. Add $25.00 for domestic shipping. Estimated Value $350 - 475. View details and enlarged photo	Realized $312
Lot 1478		Rare Partial Nest Of Three Oviraptor Eggs. This original partial nest of three complete Oviraptor eggs is 70-80 million years old, from the Djadokhta formation of Ukhaa Tolgod in Mongolia's Gobi Desert. The eggs are 6.5 inches long and belong to the largest of the two Oviraptor species called Citipati. Citipati Oviraptorids were made famous by a 1995 discovery of a fossilized nest of eggs with a mother Citipati sitting on top in a brooding position. Now displayed in the New York Museum of Natural History, it was revolutionary to discover a dinosaur perching on its eggs like a bird and only later was it discovered that Oviraptors such as Citipati also had bird-like feathers. The name Oviraptor means "egg stealer" and when first discovered in the 1920s, the paleontologists believed that they were eating eggs that they thought belonged to an early horned dinosaur named Protoceratops. Later, an Ociraptor embryo inside one of the elongated oval eggs proved them wrong. Citipati eggs are ratite in texture and have a very thin shell which is why they are rarely found complete. This nest is 14 x 7 inches on its original red sandstone base and contains three complete eggs, 6.5 inches long and 3 inches wide, with at least 80% original shell. The shell is a gray color with a thin layer of matrix covering part of the original unhatched shell. Single Citipati eggs are getting harder to locate, but multiple unhatched eggs are only available when collectors or fossil dealers are willing to sell their treasured partial nests. Add $40.00 for domestic shipping. Estimated Value $1,500 - 2,000. View details and enlarged photo	Unsold
Lot 1479		Rare Permian Age Primitive Reptile. Captorhinus magnus was one of the very first reptiles that laid its eggs on dry land (amniote) and was an early ancestor of synapsids. It is known as a stem reptile which other reptiles branched off from. Eventually, one of these branches evolved into the Archosaurs that survived the Permian extinction and gave rise to the dinosaurs much later. This impressive looking mounted specimen is a composite. The bones are carefully cleaned, matched and assembled to yield an impressive specimen such as this large 18 inch long museum quality specimen mounted on a 20 x 11 inch black matrix and having only about 15 percent restoration mostly on the ribs and delicate spines. The 270 million year old bones are found in a quarry in the arroyo formation near Lawton, Oklahoma and represent a catastrophe that killed hundreds of these reptiles at one time. The detail is excellent, particularly the large 3 x 2.5 inch fierce skull which has been prepared open to show the rows of tiny sharp teeth and also the mysterious small round hole in the center of the skull which paleontologists speculate may have allowed sunlight to enter the skull to the pineal gland. The ribs have been cemented to the matrix, adding stability to the very delicate bones and still keeping a very natural appearance that the strange reptile is crawling over the matrix. Add $75.00 for domestic shipping. Estimated Value $3,000 - 3,500. View details and enlarged photo	Unsold
Lot 1480		Rare Troodon Dinosaur Egg Nest. Troodon was a small, fast predatory dinosaur about six feet long with slender limbs and the largest brain for its size. It was feathered with long folded arms like a bird and had large sharp retractable sickle-shaped claws on its second toe, much like Velociraptor. Troodon had very large eyes (perhaps nocturnal) and excellent hearing and binocular vision. It is very rare in the fossil record, but some embryos have been found in these eggs confirming that they are from Troodon. This 11 x 9 inch partial nest of eight and one half eggs is 70-80 million years old and found at the Djadokta formation of Ukhaa Tolgod in Mongolia's Gobi Desert. A complete nest contained between 34-40 eggs laid in pairs. Troodon eggshell is extremely thin at only 1mm thickness and does not preserve well. Each egg is about 3 x 1.5 inches and has had the matrix on the shell professionally removed using small tools and a microscope revealing the textured ratite surface. These eggs are supposedly hatched, but the collapse of some of them and missing shell could also be because they are so fragile. Partial embryos have been found in eggs very similar to these. These delicate specimens were laid standing up in the sand and still retain that position in their original red stone matrix, as well as 30-50% of their original thin shell. This is perhaps a unique opportunity to add extremely rare dinosaur eggs to your collection. Add $40.00 for domestic shipping. Estimated Value $5,000 - 7,500. View details and enlarged photo	Unsold
Lot 1481		Seven Egg Unhatched Partial Dinosaur Egg Nest. The seven eggs in this partial dinosaur nest are still in the same position on the 23 x 12 inch original red limestone matrix where they were deposited by the mother duckbill dinosaur 70-80 million years ago in the Henan Province of China. This sizable and aesthetic nest is almost half a complete nest with complete Duckbill nests containing between 16-22 eggs. What makes this nest exceptional is the quality of the large 5.25 to 6 inches in diameter eggs with each unhatched egg having between 80-95 percent of its original shell and are completely natural just as found with no restoration. All dinosaur eggs are becoming more difficult to locate and completely original partial nests are in great demand. Add $75.00 for domestic shipping. Estimated Value $2,500 - 3,500. View details and enlarged photo	Unsold
Lot 1482		Seven T-Rex Teeth In Molded Jaw. T-Rex is the most famous and popular dinosaur due much in part to its size and its large serrated teeth. T-Rex teeth are considered rare and are in great demand, selling for thousands of dollars each depending on size and quality. This molded and painted section of an upper T-Rex jaw has seven real shed teeth with added cast roots to create a realistic and impressive study jaw since the real thing is not available. The teeth vary in size from 0.75 inches up to a large 2 inches. Just like those in museums, these teeth have between 10-50% restoration to them. Fortunately, the best quality teeth happen to be the largest ones. The roots have been recreated to give some idea of what the size of the teeth would be in the T-Rex jaw before they were broken off while it was feeding. Also, all seven teeth can be removed from the jaw for study. With the three larger teeth being worth more than $1,000 a piece, this molded jaw with seven total should prove to be a real bargain. Add $30.00 for domestic shipping. Estimated Value $2,750 - 3,500. View details and enlarged photo	Realized $2,300
Lot 1483		Spiny Trilobite. For protection against predators, one species of Drotops developed rows of sharp spikes all over their top shell and even over their eyes. The commonly found species of Drotops from Erfoud, Morocco does not have these sharp spines. The detail on this 4.5 x 2 inch long black trilobite is quite amazing. It took many hours of detailed work to release each and every tiny spine from their stony matrix. Dozens of spines all over the body, very tiny spines above the eyes and many individual round lenses of the compound eyes are sharp. This large and impressive trilobite is in great demand from collectors and makes for a most impressive display piece in any collection. Add $30.00 for domestic shipping. Estimated Value $1,100 - 1,500. View details and enlarged photo	Unsold
Lot 1484		Termites And Twigs Preserved In Amber. Amber is fossilized resin from extinct pine trees. Occasionally insects would become trapped in the sticky resin and be mummified (dessicated) with incredible preservation of their soft tissues, muscles, microscopic detail, and sometimes even color. Young Columbian amber is found primarily in the Andes mountain range and has not been properly dated, but this specimen is probably between 1-5 million years old. Featuring a classic golden honey color, much like Dominican amber, this extremely large 5 x 4 x 2.5 inch clear nugget weighs more than a pound at 530 grams. Its color and clarity allow for detailed study of a partial termite colony and the twigs they were eating when they were preserved. There is also an anhydro water bubble with a large drop of water contained inside. One 2.5 inch section of amber is lighter in color and slightly loose but still attached. This lighter amber was probably deposited at a later date than the main mass. Overall, this rich amber specimen is both a beautiful and interesting piece for any collection. Add $20.00 for domestic shipping. Estimated Value $850 - 1,200. View details and enlarged photo	Unsold
Lot 1485		Three Jaw Segments From Saber Toothed Fish. Enchodus was a very unusual fish that lived 70-80 million years ago in the warm seas of present day Morocco. It was a predatory fish that grew to over 15 feet in length and had large 2 inch long fang-like teeth on both its upper and lower jaws. For this reason it has come to be known as the "saber toothed herring," although it is not actually a herring. Though it was large and ferocious, it was also preyed upon by mosasaurs that were up to 60 feet long. Enchodus teeth are much rarer than mosasaur teeth which are found in the same phosphate mines of Khoribga, Morocco. The 18 x 10 inch stone matrix contains three 7-8 inch jaw segments from at least two different Enchodus and 15 teeth with the saber teeth being 2 inches or more and the smaller teeth 1-1.25 inches. In addition, there is one 3.8 inch long saber tooth with its root that is separate from the rest of the jaw segments. Add $30.00 for domestic shipping. Estimated Value $350 - 450. View details and enlarged photo	Unsold
Lot 1486		Triceratops Lower Jaw Plus Teeth. This huge 17 x 8 inch lower jaw of the popular horned dinosaur is relatively complete, though fragmented, and is quite informative as to what dinosaur finds look like. Because most dinosaur finds in the 65-67 million year old Hell Creek Formation of eastern Montana occur in ancient water channels, the bones are usually broken and scattered. This lower jaw is a great example as it was found in dozens of pieces and then put back together like a prehistoric jig-saw puzzle. This impressive jaw stands on its own with the 9 x 3 inch section of the jaw that contained the teeth with several broken teeth visible. Also, three shed Triceratops teeth .75-1 inch long found in the same area are included with this lot. This is an opportunity to purchase a large impressive dinosaur jaw without spending thousands of dollars. Add $30 for domestic shipping. Estimated Value $1,000 - 1,400. View details and enlarged photo	Unsold
Lot 1487		Triceratops Nose Horn. Not only did Triceratops have long brow horns over their eyes, but also a sharp nasal horn. This good size 6 x 5 inch nose horn was found intact on a private ranch in the 65-67 million year old Hell Creek Formation in eastern Montana. What separates this nose horn from most collected is the overall quality of the light brown bone. The horn is mostly complete except for some cracks that were filled and 2-2.5 inch section on the back of the horn that is missing only its top layer which gives access to the detailed bone quality inside the horn. The detail shows the hollow honey comb structure that enabled Triceratops to keep the weight of its enormous head down. The bone structure consisted of a lattice of bone interspersed with air which is very apparent on this remarkable fossil which also exhibits excellent microscopic detail on its bottom side.

Lot 1488		Trilobite Huge Asaphus. At 10 1/2 x 12 inches, this 475 million year old Asaphus trilobite is one of the largest and most unusual trilobites known. Something in the warm seas of Alnif, Morocco 475 million years ago caused trilobites to grow to such size (most are only 1-2 inches long). This unusual black trilobite has long curved genal spines extending outwards from its head. Placed on a 16 x 17 inch stone matrix, the quality of this notoriously poor preserved trilobite is very good with just some minor restoration on the ends of the genal spines. Add $50.00 for domestic shipping. Estimated Value $600 - 700. View details and enlarged photo	Unsold
Lot 1489		Trilobite Large Drotops. Most examples of the trilobite Drotops are only 2-3 inches long, but in the warm 375 seas near Erfoud, Morocco, this same trilobite grew to over 6 inches in length. This large 6 x 3.25 inch black trilobite has been esthtically cut out of its grey stone matrix to stand up in a life-like position on its natural 2.5 x 2.5 inch stone base. The trilobite is complete with excellent detail on the head with its bumps (postules), some hexagonal lenses in the eyes, and even the 1.25 inch mouth (hypostmore) underneath the head. Add $15 for domestic shipping. Estimated Value $300 - 400. View details and enlarged photo	Unsold
Lot 1490		Trilobite Pair of Dikelokephalonas. Both lare and rare is the pair of 475 million year old Dikelokephalonas brown trilobites from Morocco. Even a single Dikelokephalonas is a rare find but two of these interesting trilobites on one plate is indeed quite a find. The largest one is 13 x 9 inches and the smaller one 11 x 8 inches on a 19.5 x 17 inch matrix. Dikelokephalonas can be identified by the pair of unusual tail spines on its pygidium. The size and quality of these two specimens is way above average with less than 10 percent restoration on a few of the body spines, plus there is an additional 3.5 x 3 inch pygidium (tail) belonging to a third trilobite. Add $60 for domestic shipping. Estimated Value $1,000 - 1,500. View details and enlarged photo	Realized $1,050
Lot 1491		Two Foot Long Triceratops Brow Horn. With its two distinctive long brow horns and the fact that it lived at the same time as T-Rex, Triceratops has proven to be one of the most popular dinosaurs. This 24 x 7 inch brow horn is very large and from a mature Triceratops. The horns of a Triceratops are never found without cracks and are usually found in pieces. This is an excellent specimen that was found in two pieces with a complete tip needing just some minor restoration to repair some cracks. There was a 6 inch section between the two pieces that was missing. This section has been professionally restored by a paleontologist and matches perfectly. The grooves in the horn, known as the horn core, represent areas where blood once flowed. In life the horn would have been covered with keratin (like our fingernails) and would have been about 30% larger. This excellent large and heavy display fossil is 65-66 million years old and was found on a private ranch in Montana. Add $50.00 for domestic shipping. Estimated Value $1,500 - 2,000.

Lot 1492		Two Gigantic Trilobites. This magnificent museum quality slab is 22 x 17 inches and contains two of the largest trilobites that ever lived. Even more remarkable, these Acadoparadoxites sp. trilobites were some of the very first of their kind at over 500 million years old. They were one of the largest predators of the warm mid-Cambrian seas that once existed in present day Morocco. The larger of these beasts is 15 inches long and 11 inches in diameter, making it one of the largest trilobites ever found. The other specimen is 10 inches long and 9 inches in diameter. Found in Morocco's Atlas Mountain range, they have an attractive rusty orange color due to limonite (an iron oxide) which nicely contrasts the gray matrix. They are virtually complete with only minor restoration of a few of the spines on the pygidums. With most trilobites being only an inch or so in length, finding a mass mortality slab of multiple giant trilobites is a very rare occurrence. Add $35.00 for domestic shipping.

Lot 1493		Very Rare and Important T-Rex Humerus. While Tyrannosaurus Rex is the most famous of all dinosaurs, there still are a number of mysteries connected to whether it was a hunter or a scavenger and what it used its small arms for. Even though a number of partial T-Rex skeletons have been found, only a few have been fairly complete and only two have had complete arms, making this offering of a near-complete 2 foot long humerous a rare opportunity. Even though the total length of a T-Rex arm was not much longer than a human arm, its humerus was more than twice as long and twice as thick. Whatever the T-Rex used its arms for, it did not appear to be very effective as most arm bones found show evidence of having been broken and healed while the dinosaur was alive. This enormous bone is 24 inches long, 7 inches wide on the large end, and 5 inches wide on the smaller end. The bone is nearly complete with just some natural cracks and a small missing portion on the smaller end. The missing area yields a wonderful view inside the bone which reveals a honeycomb-like structure that is distinctive in T-Rex bones and that was necessary to make the bones lighter in such a massive creature. This 65 million year old humerus is one of the largest, if not the largest, T-Rex humerus specimens known and was found in the Hell Creek Formation on a private ranch in northern Montana.

Lot 1494		Woolly Mammoth Tusk. Complete tusks from a woolly mammoth Mammuthis primigenius are rare. This complete 22 inch long 1.5 inch diameter tusk is from a juvenile Mammoth that was most likely a male because of its size. It has been polished to reveal various shades of brown with patches of cream colored ivory. These colors resulted from the original white ivory being mineralized over thousands of years by minerals such as vivianite and iron phosphate. This museum quality tusk was found in the Taymyr Peninsula of Siberia and is between 30,000 and 100,000 years old. Most recovered Mammoth ivory is found in broken pieces unlike this exceptional specimen which comes with its own display stand. Add $40.00 for domestic shipping. Estimated Value $1,300 - 1,600.

Lot 1495		Wooly Mammoth Hair and Ivory. This large specimen of 30,000 year old Wooly Mammoth hair comes from the only Mammoth specimen available from about a dozen frozen Mammoth carcasses that have been found in the frozen permafrost of the Indi-girka Basin of Siberia. Hair does not fossilize and therefore is extraordinarily rare in extinct animals and definitely contains much original DNA. This specimen contains much more hair than usually offered and has examples of the long reddish-brown hair that covered the body of the Mammoth as well as a clump of the soft tan colored inner hair. Also included in the 8 x 6 inch Riker mount is a 6 x 1.5 inch section of fossilized Mammoth Ivory that is dark brown on the outside and ivory colored on the inside. This rare specimen of Mammuthis primigenius hair was part of the collection of Dr. Gennady Baryshnikov of the USSR Academy of Sciences in Leningrad, Russia. Add $15 for domestic shipping.

Lot 1496		Wooly Mammoth Tooth. Wooly Mammoths (Mammuthus primigenius) had the largest individual teeth of any animal that ever lived. Mammoths had six pairs of molars in both their upper and lower jaws during their lifetime, each one larger than the preceding one. This gigantic 14 x 6 inch near perfect molar was one of the very last sixth molars. The dark brown color and superb smooth surfaces with no chips is very unusual for Mammoth teeth and the root is virtually complete with just a couple of minor chips on the end. Most Mammoth teeth come from the North Sea where they are dredged up in fishing nets resulting in sea damage, cracks and missing pieces, but this museum quality tooth is 30,000-75,000 years old and was found in the frozen tundra of Siberia, Russia where the best preserved Mammoths are found.
