Lot 506		AMMONITE WITH THREE OYSTERS ATTACHED. This complete 100 million year old large 10 inch diameter ammonite, Pervenquivia is not only an attractive golden color with excellent detail but it has three oysters, Exogyra sp., attached to it. This is a very rare association fossil where after the ammonite died and its shell settled on the ocean bottom, three oysters attached themselves to its shell and were later buried under the sea bottom and preserved in Grayson County, Texas for the next 100 million years until being dug up. The oysters are a light brown in color and are nicely contrasted against the golden ammonite. Add $15 for domestic shipping. Estimated Value $450 - 550. View details and enlarged photo	Unsold
Lot 507		CARCHARODONTOSAURUS DINOSAUR TOOTH. Huge 3.75 inch long by 1.75 inch wide complete dinosaur tooth of Carcharodontosaurus saharicus, the T-Rex of Africa. Even though Carcharodontosaurus was even larger that a T-Rex, most of the teeth found are only 1.5 to 2.5 inches long. This excellent brown tooth is not only long by very wide also with most of its enamel present with only minor enamel chipping which almost always occurs. The all important serrations are sharp and complete except for one small area and the tip is complete with just a little wear that happened when the theropod dinosaur was alive. This very large impressive tooth was found in the Sahara desert of Morocco and are older than a T-Rex at 70-80 million years old. Housed in a 8 x 6 inch Riker mount. Add $15 for domestic shipping. Estimated Value $800 - 1,300. View details and enlarged photo	Unsold
Lot 508		COMPLETE FINGER OF HUGE GROUND SLOTH. Ground sloths in North America grew to great size before becoming extinct. Glossotherium chapadmalense was more than 13 feet tall and lived 1-2 million years ago in Taylor County, Florida. This gigantic rare black 8.5 inch long finger has a 5.5 inch slightly curved claw missing just a small part of the tip plus a robust 3 x 2 inch finger bone. These huge claws were used for defense against predators and to dig up roots. Glossotherium could stand upright and was mostly a vegetarian but it also occasionally ate meat. Ground sloths also have an important place in the history of paleontology in the U.S. as president Thomas Jefferson wrote a letter in August, 1796 about a large claw that he found from a ground sloth and this extinct animal was named after him, Megalonyz jeffersoni and marked the beginning of vertebrate paleontology in the United States.

Lot 509		COMPLETE PSITTACOSAURUS DINOSAUR. Psittacosaurus is a very important dinosaur that lived between 120-130 million years ago in Liaoning Province, Central Asia. Psittacosaurus is important as being the oldest ancestor of the famous horned dinosaurs such as Triceratops. Psittacosaurus did not have horns but did possess a horned beak and bony Jugals (back of the upper jaw) which are characteristic of only ceroptopsian (horned) dinosaurs. Psittacosaurus was a very small dinosaur being only 4-5 feet long as an adult. This 24 inch long juvenile is the smallest mounted dinosaur ever offered at auction. The great preservation of the small delicate bones occurred because this dinosaur was instantly buried under volcanic ash over 120 million years ago, a sort of dinosaurean Pompei It has been mounted in the life-like position of the Psittacosaur as displayed in the New York Museum of Natural History and has no external armature but has thin rods inserted in the bones, stands on rods in its feet and makes for a costly but amazing display. Approximately 70-75 percent of the dinosaur is real bone including all of the legs, claws, body, vertebrae, skull with only the ribs, neural spines and the end of the tail being professionally cast. Most dinosaurs in museums that are real usually contain only 10-40 per cent real bone. The all important skull is 2.5X2.5 inches in good condition (not distorted or compressed) with six reel teeth on one side of the jaw. This small complete dinosaur would make an excellent desk top display and comes with instructions for easy assemblage in the provided wooden base (takes about 5 minutes) as there are seven sections that can be easily removed for study, the four legs, body, tail, and skull. The skull can be removed for study or to show amazed friends. Add $75 for domestic shipping. Estimated Value $10,000 - 14,000. View details and enlarged photo	Unsold
Lot 510		DINOSAUR EGG MUSEUM QUALITY. This prepped complete unhatched Duckbill dinosaur egg is 70-80 million years old 6. x 5 inches and of museum quality with over 90 percent of its original shell intact. The egg is completely original and has been professionally airbrushed to remove all of the minerals covering the original shell leaving the shell exposed with its deep chocolate brown color. We do not know what Duckbill species this egg belongs to, but being the largest Duckbill egg it might belong to the huge Duckbill dinosaur Shantungosaurus which reached more than 50 feet in length and has been found in the same area in Henan Province of China. This museum quality dino egg makes an excellent display still standing on a small section of its reddish brown limestone matrix. Add $25 for domestic shipping. Estimated Value $650 - 850.

Lot 511		DINOSAUR RAPTOR FOOT CLAW. Chirostenotes (its name means slender hands) is a rare small raptor-like therapod of which not a lot is known. It is known mostly from its claws which are quite large and formidable. It is part of the little known Elmisaurid family of dinosaurs which may have been similar to a Dromaeosaurid Raptor or perhaps an omnivore which ate mammals, insects and plants. Whatever it was it was very fast and had large impressive claws such as this 3.75 inch (measured along the curve) foot claw. This is a lovely well detailed brown claw with excellent detail and smooth surfaces with just the end of the tip being restored. This rare and unusual dinosaur claw is about 70 million years old and was found on a private ranch in SW Montana in the Hell Creek Formation. Comes housed in a 8 x 6 inch Riker Mount. Add $20 for domestic shipping. Estimated Value $1,250 - 1,600. View details and enlarged photo	Unsold
Lot 512		ENORMOUS SPINOSAURUS HAND CLAW. Made famous in "Jurassic Park III" as the dinosaur that killed a T-Rex, the enormous theropod dinosaur Spinosaurus with a huge sail on its back remains an enimagmatic dinosaur as no skeleton even remotely complete has been found and the only partial skeleton was destroyed in World War II. Spinosaurus is mostly known from its teeth which are fairly common but usually broken and ugly. Claws are rarely found and big claws such as this 6 inch complete museum quality hand claw (measured along the curve) showing all of the blood grooves with a perfect tip and no restoration are only seen in museums. Claws are much rarer than teeth because the dinosaur could replace its teeth but not the claws. This 80 million year old dinosaur claw was found in the Kem Kem Valley near Taouz, Morocco (near the border with Algeria). This museum quality fossil is housed in a 8X6 inch Riker mount. Add $20 for domestic shipping. Estimated Value $3,000 - 4,000. View details and enlarged photo	Realized $2,875
Lot 513		FAMOUS AMERICAN TRILOBITE ARCTINURUS. Arctinurus boltoni is a unique famous American trilobite that is both rare and striking in appearance with its wide wing-like body and its entire body covered with tiny raised lumps called postules that may in life had sensory whiskers to detect prey animals when it buried itself in the ocean bottom similar to what some flatfish and rays do. This museum quality specimen is 4 x 3.25 inches on a 8.25 x 6.25 inch dark gray shale matrix and complete with excellent head, eyes and raised postule detail. There are no other trilobites found anywhere in the world that look like this unusual 420 million year old black arthropod and it was found in only one location in Middleport, New York which is near Buffalo and this quarry has been permanently closed further adding to the high demand from fossil collectors. Add $20 for domestic shipping. Estimated Value $1,800 - 2,200. View details and enlarged photo	Unsold
Lot 514		GIANT COMPLETE AMMONITE. Ammonites are extinct cephalopods that somewhat 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 10.5 x 8.5 inch Cleoniceras ammonite is 110 million years old from the island of Madagascar and is complete with hues of light to dark brown on its polished outer surface as well as some of the original mother of pearl in the center. It is one of the most striking museum quality ammonites with most of its surface covered with a fern shaped suture pattern that is outlined in a light cream color giving excellent contrast. Ammonites calcium carbonate shell was strengthened by the interlocking suture pattern and because of this it did not have to be so thick to resist the water pressure when the ammonite would dive in deeper water. Each species of ammonite had its own distinctive sulture pattern and can be identified just from its sutures. This ammonite has both size and beauty. Add $15 for domestic shipping. Estimated Value $575 - 750. View details and enlarged photo	Unsold
Lot 515		GIGANTIC DIKELOKEPHALONAS TRILOBITE. Dikelokephalonas is one of rarer 475 million year old trilobites found in Morocco and also one of the largest. This complete trilobite is 10.5 x 9.25 inches and is nicely centered on a 13.5 x 12 inch beige and gray matrix. Dikelokephalonas can be identified by the odd shaped pair of tail spines on its pygidium. The detail on this trilobite is sharp and clear with the only defect being a crack in the matrix running through the right part of the head of the trilobite that has been professionally repaired and is barely noticeable. All in all this is a premium quality specimen that is seldom found better preserved. Add $25 for domestic shipping. Estimated Value $500 - 650. View details and enlarged photo	Unsold
Lot 516		HUGE 17 INCH FISH. Some of the best preserved fish in the fossil record are found in the 50-52 million year old Green River Wyoming fossil fresh water lake beds. The vast majority of the fish found are small measuring only 2-4 inches long. This museum quality lot is the exception with a huge 17 inch long (close to the maximum size) Diplomystus which was an extinct member of the herring family. The huge fish is complete with outstanding skin, fins and even some sharp little teeth in its distinctive upturned mouth which enabled it to feed on small fish and creatures near the surface of the lake. The dark brown fish is nicely contrasted on the cream colored 19 x 10 inch sandstone matrix. Also, there is a complete 3 inch Knightia on the same matrix. Add $25 for domestic shipping. Estimated Value $800 - 1,000. View details and enlarged photo	Realized $748
Lot 517		HUGE 26 LB CRINOID SPHERE. This immense 8.5 inch diameter bowling ball size sphere weighs over 26 pounds and is almost composed entirely of hundreds of plates of crinoid stems that are 150 million years old from Henan Province, China. Crinoids are echinoderms, relatives of starfish and are mostly known from the plates that made up their long stems that were attached to the ocean bottom as they filter fed on small organic creatures. These stems easily broke up into the individual round plates when the crinoid died and in some areas comprise 99% of the fossils found in the rocks. The crinoid stems range in shape from straight sections to round and oval and in color from shades of pink to browns and blacks. Because of the rare pink color of some of the stems, this stone is known as pink marble. Add $20 for domestic shipping. Estimated Value $400 - 550. View details and enlarged photo	Unsold
Lot 518		HUGE FOSSIL BADLANDS TURTLE. Stylemys nebrascensis was a 30 million year old turtle that roamed the White River Formation of the Badlands of South Dakota. This huge 15 x 12 inch turtle is one of the largest ever offered at auction. The average size is usually only 5-8 inches long. The white outer carapace is remarkably complete with only a few plates moved slightly from the millions of years of fossilization. Stylemys� carapace was formed by a series of scutes made of keratin originally. Keratin is the same material that our finger nails are made of. About 80 percent of the underside of the turtle, the plastron, which was formed by bony plates is preserved along with some white leg bones which are clearly still buried in the matrix. The shape and appearance is of museum quality with little distortion of the shape of the outer shell. A rare opportunity to buy a really large museum quality turtle. Add $40 for domestic shipping. Estimated Value $800 - 1,000. View details and enlarged photo	Unsold
Lot 519		HUGE STARFISH MASS MORTALITY PLATE. Finding a complete starfish is not easy because the delicate arms break off quite easily during the fossilization process. Finding a mass burial of more than 28 complete starfish is extraordinary. This huge 29" x 22.5" museum quality plate is 475 million years old from Lkaidrami, Messeu, Southern Morocco. This magnificent sea bottom slab preserves a snapshot of what life existed on the sandy bottom of the warm seas of Morocco 475 million years ago before being buried by mud or volcanic ash. There are more than 24 brittle stars (ophiuroids) up to 4 inches in diameter. Brittle starfish usually hang in groups and attach themselves to the sea bottom and filter feed on small creatures that float by. Also, there are three asteroid starfish intermingled with the brittle stars. The largest of these typical starfish is 3 inches and one of them even has a speckled, spotted pattern which would have been some color pattern when the starfish was alive, but color does not fossilize. Completing this remarkable 100% natural slab is a single one inch long trilobite. This is a rare opportunity to acquire both a rare and dramatic fossil for both display and study. Add $65 for domestic shipping. Estimated Value $1,200 - 1,700. View details and enlarged photo	Unsold
Lot 520		HUGE TOOTH FROM LARGEST SHARK. Carcharodon megalodon was the largest shark that ever lived growing to more than 50 feet long, perhaps much more. Megalodon ate whales whose vertebrae and teeth are often found along with megalodon teeth. This gigantic 6 inch long megalodon tooth measured on the diagonal has excellent greenish brown enamel and an intact brown root. The enamel is far above average with only a few cracks and a few minor chips at the top by the root. The all important serrations are completely intact and rather sharp which is quite rare for such a large tooth. This is the largest Carcharodon tooth that you can but without paying a fortune for a tooth just .25-.50 inch bigger. This immense tooth is about 15 million years old and was found in the muddy river waters of South Carolina by intrepid divers who have to locate the teeth by feel since there is no visibility at the river bottom. Add $15 for domestic shipping. Estimated Value $850 - 1,050. View details and enlarged photo	Unsold
Lot 521		LARGEST PLANT EATING DINOSAUR EGG. The rare eggs of the sauropod Saltosaurus from Argentina are the largest known plant eating dinosaur eggs. This beautiful dark brown 8.75 x 8.25 x 4 inch egg is much larger than the 6-6.5 inch sauropod eggs known from China. This rare 80-90 million year old egg comes from Salta, Argentina and because of dinosaur embryonic bones is known to be from the Titanosaur known as Saltosaurus. This 40 foot long giant had the typical sauropod shape with a long neck but also had bony armor in its skin along its back and tail. Saltosaurus eggs are in great demand due to their rarity and usually are found unhatched, agatized and round like a bowling ball and sell for many thousands of dollars. This somewhat compressed specimen has been hatched but still contains more than 90 per cent of its original thick shell. For whatever reason, the shells of the last dinosaurs neat the end of the Cretaceous had much thinner shells. From an old collection, this is a rare opportunity to purchase a very rare dinosaur egg. Add $35 for domstic shipping. Estimated Value $2,200 - 2,700. View details and enlarged photo	Realized $2,013
Lot 522		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 but even more importantly helped to 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 25 inch long fossil on a 23 x 9 inch limestone matrix is from the Irati Formation of Brazil. The attractive brown bone has excellent 3D detail of the vertebrae, rib bones, delicate neural spines and the crocodile-like skull that is preserved in a side view with several small sharp teeth visible in the clenched jaw. This considerably above average specimen is missing three of the legs and a few bones at the tip of the tail. This fossil Mesosaurus has both size and exceptional bone quality with the average Mesosaurus being only 12-16 inches long . Add $35 domestic shipping. Estimated Value $1,500 - 2,000. View details and enlarged photo	Realized $1,265
Lot 523		MUSEUM QUALITY PLATE OF 5 LARGE CRINOIDS. Crinoids are related to star fish and are known as "sea lilies" because they resemble plants more than animals. Scyphocrinites was an interesting floating crinoid with its stem attached to a round air-filled bulb called a lobolith that floated on the surface of the ocean 425 million years ago in the warm seas near Tafilalet, Morocco. When the crinoids died they would separate from their flotation bulbs and settle on the ocean bottom. The flotation bulbs would continue to float away and are never found together with the crinoid crowns and stems. This magnificent grouping contains 5 complete dark grey crinoid crowns(heads) the largest being 6 x 3.5 inches also a 4 x 3 inch crown with a 7 inch stem some and three others some with partial stems and all having detailed feather-like feeding arms and a mosaic of small intertwined calcite plates forming the crown. This esthetic grouping of multiple crinoids nicely contrasted on a 20 x 14 inch brown stone matrix would be one of the highlights of any fossil collection. Add $50 for domestic shipping. Estimated Value $850 - 1,150. View details and enlarged photo	Unsold
Lot 524		PAIR OF ARMORED FISH SHIELDS. Zyxhaspis sienmoradzkii was one of the primitive armored jawless fish that swam in the 375 million year old Eurypterid invested oceans near the present day Ukraine. Fish needed protective armor to survive the ferocious attacks of the top predator of their day, the sea scorpions which could reach lengths of over 10 feet. Zyxhaspis belonged to the genus Cephalsaspid and was a slow bottom feeding fish with eyes on the top of its skull and armor protection only its head with the rest of its body and fins being unprotected. This excellent 8 x 6 inch plate contains two complete head shields 4 x 3 and 3 x 2.75 inches with their eye holes and some of the tiny patterns of light armor outlined in white calcite on the brown matrix. There is also part of a third disarticulated fish skull which is the normal condition found with complete head shields being rare. Add $25 for domestic shipping. Estimated Value $1,000 - 1,500. View details and enlarged photo	Unsold
Lot 525		PARTIAL SKELETON OF 30 MILLION YEAR OLD OREODONT. Merycoidon culbertsoni was a strange early mammal of an extinct group of ruminants known as oreodonts that was only found in North America that had some features like a pig and some features like a camel or deer. Oreodonts are Artiodactyls which are even toed ungulates. The skull was somewhat pig-like with its enlarged canine teeth but the skull had pits in front of its eyes very similar to a modern deer. While skulls from Merycoidon are found regularly, near complete skeletons are unbelievably rare. This museum quality professionally prepared specimen has only about 5% restoration and consists of an excellent 8 inch skull, two near complete 18 inch long rear legs with several disarticulated claws, 18 inch long body and back vertebrae with several rib bones. This spectacular specimen is completely from one animal and has been prepared in the same position as when it died over 30 million years ago. The all important skull is excellent with almost all of its original teeth including one of the one inch long canines. This museum quality fossil was found in the Brule formation of the White river area of South Dakota and is a rare opportunity to purchase an esthetically attractive and important early mammal fossil. Add $85 for domestic shipping: $85. Estimated Value $2,500 - 3,000. View details and enlarged photo	Unsold
Lot 526		PETRIFIED WOOD STUMP FROM RARE TREE. This large 14 x 10 x 10 petrified wood stump is from one of the rarest and perhaps new species of Woodworthia conifer tree from the famous 210 million year old Chinle Fromation in Northern Arizona. This unusual extinct conifer tree has an unusual type of bark which is beautifully preserved on this museum quality specimen with a series of bumps all the way around the trunk that when the tree was alive were a series of small .25 inch in diameter holes that had small branches growing from them. The wood from the Woodworthia tree had no growth rings like most trees do, but the entire 10 inch in diameter top of this trunk has been polished to show the radiating structure with delicate tans, creams and white color. No leaves have been found from the extinct Woodworthia tree so that its reproductive structures are unkown. This is both a rare and lovely piece of petrified wood with complete bark and polished structure. Add $50 for domestic shipping. Estimated Value $500 - 750. View details and enlarged photo	Realized $391
Lot 527		PREMIUM QUALITY PAIR OF OVIRAPTOR EGGS. This original pair of complete Oviraptor eggs is 70-80 million years old from the Djadokhta formation of Ukhaa Tolgod of Mongolia. These eggs were found in the Gobi desert and are 7.25 inches long and belong to the largest of the two Oviraptor species called Citipati to distinguish this difference from the other smaller species. Citipati Oviraptorids were made famous by the nest of eggs with the mother Citipati sitting on top of the eggs in a brooding position. This famous specimen is displayed in the New York Museum of Natural History and was discovered in 1995. It was revolutionary to discover a dinosaur sitting on top of its eggs like a bird and only later was it discovered that Oviraptors such as Citipati also had feathers like a bird. Citipati eggs are ratite in texture and have a very thin shell which is why they are rarely found complete. This premium quality pair of eggs has sharp textured detail on the shell and about 90% original shell on one and 60% shell on the other egg. The shell is a dark gray color which nicely contrasts the 10 x 9 inch red limestone matrix. There are probably three or more species of Oviraptor type dinosaurs that had eggs that vary in size from 5-7.5 inches, but these classic eggs definitely belong to the species of Oviraptor, Citipati first found in the 1920�s in Mongolia. Add $40 for domestic shipping: $40. Estimated Value $1,200 - 1,500. View details and enlarged photo	Unsold
Lot 528		RARE ARMORED FISH. 375 million years ago there was an arms race going on in the oceans between fish and the fierce predatory sea scorpions know as Eurypterids. Most fish were slow swimming jawless bottom feeders and developed thick body armor to protect themselves from attack from the scorpions. Some of the best armored fish such as this 5X4 inch Bothriolepis Canadensis had their entire head, body and even their pectoral fins covered in a thick patterned bony armor with only their tail exposed. This large Bothriolepis specimen was found near Miguasha Bay in Quebec, Canada excellently preserved on a 7 x 8 inch grey slate slab with one of its two 4 inch long armored pectoral fins perfectly preserved and very fine detail on all of the armored plates covering the head and body. These important interesting fossils can no longer be obtained from the quarry and only are available when collections are sold. Add $15 for domestic shipping. Estimated Value $1,800 - 2,200.

Lot 529		RARE GROUPING OF CHINESE TRILOBITES. This very large 22 x 9.5 inch black slate slab contains the mass mortality remains of nine trilobites belonging to three different species rarely encountered and missing from most collections. All nine of these white trilobites are 480 million years old from Hunan Province, China and have a white calcite covering which shows up really well on the black slate. There are three different species of trilobites present on this slab with the superb 7 inch long specimen being Xiangxiaa, the "hammerhead" shaped heads being Szechuanella and the ones with spines being Asaphinas. All of the trilobites on this rare plate are 3D except for one which was preserved upside down and is recessed into the matrix. Add $35 for domestic shipping. Estimated Value $500 - 750. View details and enlarged photo	Unsold
Lot 530		RARE PAIR OF TROODON DINOSAUR EGGS. Troodon was a small predatory dinosaur about six feet long, was fast with long slender limbs and had the largest size brain for its size of any dinosaur. It was feathered with long folded arms like a bird and had large sharp retractable sickle-shaped claws on its second toe 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 indeed Troodon. These two 2.85 x 1.5 inch Troodon eggs are 70-80 million years old from the Djadokta formation of Ukhaa Tolgod of Mongolia and were found buried in the Gobi desert. Troodon eggshell is extremely thin at only 1mm thick and does not preserve very well but both of these eggs appear to have more than 50% of their original shell although half of one of the eggs is still buried in the matrix. Embryonic bones have been found in at least one of the eggs from the partial nest that contained both of these eggs. These delicate eggs were laid standing up in the sand and still retain that position in their original 4X5 inch red stone matrix. This is perhaps a unique opportunity to add extremely rare dinosaur eggs from a known rare dinosaur to your collection. Add $25 for domestic shipping. Estimated Value $1,250 - 1,500.

Lot 531		RARE RANILLA FOSSIL CRAB. The strange shaped extinct Ranilla crab (known as frog crabs) are rare small primitive crabs from the Raninidae family that have adapted their body and claws to deep water. These two specimens are 1.5 x 1.2 inches sitting on a 2 inch stone matrix and have a full carapace, both unusual claws and many legs and mouth parts as well. The large flat claws were modified into tools that the crabs used to dig into the mud at the bottom of the ocean to hide from predators. Even the odd rounded carapace aided quick burial. These rare crabs are 2-4 million years old and only found in one place in the world, Liberty County, Florida. A single specimen sold for $975 several years ago. Add $15 for domestic shipping. Estimated Value $375 - 500. View details and enlarged photo	Unsold
Lot 532		T-REX TOOTH HUGE 3.25 INCHES. This 3.25 inch long T-Rex tooth is not only large but also pristine with an excellent tip, serrations and no repair. Only a few cracks have been filled as is usual for all T-Rex teeth found. The tooth is rather thick, has sharp squared serrations which define it as a T-Rex, and even shows a slight indentation at the root level on one side which is from a replacement tooth that was already growing behind this tooth when it was broken off when the T-Rex was feeding. All T-Rex teeth are shed teeth except the very few that are found with the dozen or so partial skeletons that have been found. This impressive and rare tooth was found in an ancient river or lake bed on a private ranch in the 65-67 million year old Hell Creek Formation of Montana. All T-Rex teeth are in great demand, but those very few that are not broken and repaired with pristine tips are rarely encountered. Add $20 for domestic shipping. Estimated Value $4,500 - 5,500. View details and enlarged photo	Unsold
Lot 533		TERMITE COLONY AND TWIGS IN YOUNG COLOMBIAN AMBER. Amber is the fossilized tree resin. Some trees produce resins to help heal breaks and gashes. Occasionally insects become trapped in the sticky amber and are mummified (dessicated) with incredible preservation of soft tissues, muscles, microscopic detail and sometimes even color. DNA has been retrieved from amber over 65 million years old at the time of the dinosaurs. The age of amber itself cannot be determined. Only the rock it is deposited in can be tested. Colombian young amber is found mostly in the Andes mountains in remote regions and has not been properly dated. The amber with the classic golden honey color like Dominican Amber is probably between 1- 5 million years old. Such is the probable age of this extremely large, 6 x 4.5 x 4.5 inch clear amber nugget weighing almost 3 pounds (2.86lbs). This magnificent piece contains more than 100 termites, termite larvae, twigs, and even other insects such as millipedes and flies. There must have been a termite mound beneath this pine tree millions of years ago and a portion of the mound was covered and trapped in the sticky resin when the tree was injured This rich golden amber nugget is both beautiful and massive being one of the heaviest amber pieces ever auctioned.

Lot 534		TWO GIGANTIC TRILOBITES. This lot consists of both the positive and negative slabs of Acadoparadoxites, one of the largest and one of the very earliest trilobites that ever lived. It is very rare to collect both the positive and negative slabs as most specimens only contain the positive when the rock is split. This gigantic trilobite was one of the largest predators of the mid Cambrian warm seas of Morocco. Found in the Atlas Mountain range of Morocco, this 14 x 10 inch trilobite has an attractive rust orange color, limonite (an iron oxide) which nicely contrasts the grayish brown matrix. Both parts are virtually complete with only minor restoration of a few of the spines on the pygidiums. With most trilobites being only an inch or so in length, finding a museum quality specimen of a giant trilobite is a very rare occurrence. Add $35 for domestic shipping. Estimated Value $550 - 800. View details and enlarged photo	Unsold
Lot 535		WALLISEROPS TRIDENT TRILOBITE. Walliserops is one of the more bizarre of the spiny trilobites of Morocco. What makes it so strange is the trident shaped appendage on the front of its head. What this was used for is pure conjecture with digging in the soft ocean sand being the most likely. The highly detailed professional preparation on this complete 3 x 1 inch 380 million year old trilobite from Ikelel Gara, Sountern Morocco is as good as it gets with a 3D trident prepared in a life-like position raised above the matrix, rows of raised tiny spines including the long curved spines on the backs of its compound eyes and excellent outstretched positioning on the 4 x 4 inch smoothed beige matrix. This magnificent weird looking trilobite would highlight any fossil collection. Add $15 for domestic shipping. Estimated Value $1,000 - 1,250. View details and enlarged photo	Realized $920
Lot 536		WOOLLY 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 new molar would be larger than the preceding one and this gigantic 8 x 11.5 inch near perfect molar was one of the very last sixth molars. The flat part of the tooth with the alternating enamel and dentine layers is 8 inches long, the huge 11.5 inch root is virtually complete with just a couple of minor chips on the end and the whole tooth is a rich dark brown color with very smooth surfaces with no chips as normally found. 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.
