90 Million Year Old Insects. Insects usually do not fosillize very well unless they die in water or amber and are usually small in size. This collection of six large insects come from the 90 million year old Crato formation of Brazil and became fossilized from being buried in a lake bottom. All of the insects have been left in their cream colored limestone matrix. The collection consists of a 1.25 inch grasshopper, a 1.0 inch cricket missing its head, a 1.0 inch flying insect with outstretched wings with excellent vein detail in the wings, a .75 inch moth with wings facing backward, a .6 inch beattle and a .5 inch cockroach. The quality of these insects is similar to that of the Solnhofen insects that sell for hundreds of dollars each.

Ammonite Sculpture. Ammonites were cephalopods that looked liked a squid in a spiral shaped shell. This esthetic 14.5 x 7.5 inch sculpture features two 100 million year old golden brown ammonites, Phylloceras from Sidi Yahya Said, Morocco positioned atop a 6 inch long base containing a 2.75 inch long spiral ammonite. The large Phylloceras ammonite is a very large 10 inches in diameter and beautiful with colors blending from cream to golden brown and inner chambers looking like the inside of a geode with tiny brown calcite crystals. The smaller 4.5 inch ammonite has colors blending from cream to orange to light gray. The walls of some of the chambers (called Septa) have dissolved away leaving the squiggly pattern of the sutures which strengthened the ammonites shell when it was alive. The back side of each ammonite is solid and clearly shows the colorful golden brown suture lines. Photos do not do justice to this exquisitely colorful and ornate ammonite sculpture which has both natural and esthetic beauty.

Ankylosaur Foot With Hooves. Armored plated Ankylosaurs with their huge clubs on their tails are one of the most recognizable dinosaurs, but despite their popularity any fossil from them except for their armored skutes is rare. Their fossils are rare because they did not live in herds or close to lakes and streams where most of the fossil dinosaurs are found. This rare front foot consists of three toes each 2 inches long with a small hoof at the end of each toe. The three toes are 2 inches wide. The particular species is Shamosaurus 90-120 million years old from the Gobi Desert of Mongolia. Shamosaurus was between 15-20 feet long when fully grown. All of the bones exhibit a lovely light brown color and are original with no restoration and are mounted in a 8 x 6 inch Riker Mount. This is the first time Ankylosaur foot bones have ever been auctioned.

Carcharodon Megalodon Shark’s Tooth. Carcharodon megalodon was the largest shark that ever lived growing to more than 50 feet in length and ate whales whose bones are found right alongside with the huge teeth of megalodon. This immense 6.35 inch, 15 million year old Carcharodon tooth was found in the muddy river waters of South Carolina. Estimating the length of a shark at about 10 feet in length to every one inch of tooth, this behemoth would be over 60 feet long. This huge tooth is one of the largest ever to be auctioned but does have some chipping on the front enamel, minor chipping on the blades and about 10-15 % restoration mainly on the front root and the back enamel. This is an opportunity to purchase a really huge shark’s tooth without paying well over $1000.

Complete Mammoth Tusk. Complete tusks from a wooly mammoth Mammuthis primigenius are rare. This large complete 38 inch long 3 inch diameter tusk is from a juvenile Mammoth most probably a male because of its length and small diameter. It has been lightly polished revealing mostly chocolate brown colored ivory. These brown colors resulted from the original white ivory being mineralized over thousands of years with 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 just broken pieces unlike this over 3 foot long curved exceptional quality tusk. The only ivory that can be legally sold is fossil ivory. Comes with a display stand.

Crinoid and Ammonites. The 180 million year old Posidonia Shale of Holzmaden is famous for the exceptional preservation of fossil sea creatures. The black slate is a perfect matrix for the golden brown fossils that are occasionally encountered. This large 26.5 x 20 inch black slate matrix contains a beautiful large 19 inch Crinoid, Seirocrinus subangaris which consists of a 5 inch diameter Calyx (flower) and a 12 inch long curving stem. Crinoids, known as sea lilies, look like a plant but are actually animals related to starfish and have a five fold symmetry. They open their arms and filter feed small animals and detritus. Also on the matrix are 11 golden brown ammonites, Dactylioceras commune, ranging in size up to 3 inches in diameter. The large crinoids are quite rare and in tremendous demand both with collectors and decorators. A barely noticeable break in the black slate has been professionally repaired and backed with wood for stability. Large crinoid plates such as this one have sold for more than $10,000 at auction.

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 which 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, having much more original egg shell than normally found and still standing on a small section of its reddish brown limestone matrix.

Dinosaur Tail Vertebrae With Bite Marks. This large 7.5 x 8 inch Duckbill dinosaur (probably Edmontosaurus) tail vertebrae is nearly complete but what makes it very special are four tooth marks that were made by a massive meat eating dinosaur probably T-Rex or one of the other few really large tyrannosaurs like Daspletosaurus or Albertosaurus that were present in Garfield County, Montana 67 million years ago when this fossil was buried in a river basin. Only a few tyrannosaurs had enough jaw strength and strong enough teeth to bite through solid bone. The tails of hadrosaur dinosaurs were massive with a lot of muscle that would certainly made a good meal for a tyrannosaur dinosaur. The large tyrannosaurs like T-Rex just bit into and swallowed both meat and some bone when they fed. There is no way of determining if this Duckbill dinosaur was actually killed or just scavenged by the tyrannosaur but this fossil bone does give some indication of the power of the jaws of the large predatory tyannosaurs.

Five Large Crinoids on One Plate. 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 and three others 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.

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.

Gigantic Trilobite. Burmeisterella is not only a very rare spiked trilobite but also one of the largest trilobites that ever lived. This enormous trilobite is 19 x 9.5 inches making it one of the largest trilobites ever offered for sale. Burmeisterella is 375 million years old from Morocco and usually only 7 to 10 inches in length with the only other specimen that was 19 inches long being sold for $9000. Even at this gigantic size Burmeisterella still had long spikes on its eyes and down the length of its body for protection from predators. This attractive black trilobite has most of its spines although there definitely is restoration on the spines as no specimen is ever found complete with all of the spines intact. With most trilobites being only 1-2 inches long, this monster looks like a dinosaur compared to a chicken in size. Definitely, this trilobite would be the highlight of any fossil collection.

Horseshoe Crab in a Death Spiral. Horseshoe crabs, a close ancestor of the trilobite, are very rare in the fossil record with the best preserved specimens such as this one being found in the 150 million year old lithographic limestone of the Solnhofen Lagoon (Eichstadt, Germany). Not only is this 4 inch long golden Horsehoe crab, Mesolimulus walchi complete and well preserved but the very last seconds of its life are captured also in its death spiral represented on this large 15 x 12.5 inch creamy limestone slab. The death spiral ending with the Horseshoe crab fossil is a slightly lighter color on the slab from the sandy Lagoon bottom being disturbed by the suffocating crab. This occurred because the Lagoon water was oxygen depleted and any sea animals tossed into it by storms were quickly suffocated. Finding a fossil with a story to tell about its becoming is a fossil is extraordinary.

Ichthyosaurus Paddle and Vertebrae. Ichthyosaurs were fast swimming reptiles that resembled dolphins. This lot contains a near complete fore paddle (pectoral) and also two vertebrae and several more disarticulated phalanges. This species Ichthyosaurus communis from Lyme Regis, Dorset England was the first species of Ichthyosaur discovered in 1918 by Mary Anning who became the very first fossil dealer and inspired the ditty "she collects sea shells at the sea shore.".Ichthyosaurus is 190 million years old and would have been about 5-6 feet long as an adult. This well detailed 14 x 7.5 inch dark grey matrix contains an articulated paddle which is really the fingers of the Ichthyosaur which kept adding phalanges to create a paddle which was used for steering while it was swimming. While we only have three phalanges in our fingers, Ichthyosaurus had up to 15 phalanges as you can count in this specimen. The large number of phalanges also identifies it as a front pectoral paddle as the rear paddles had fewer phalanges. While ammonites are common from Lyme Regis, any bones from Ichthyosaurs are rarely found and in great demand.

Large Ammonite Cut Pair. Ammonites were early mollusks that somewhat resembled an octopus or squid living within a protective shell and are the closest relative to the chambered nautilus which still exists today. This specimen contains both halves of a large 7.75 inch in diameter 110 million year old ammonite, Cleoniceras from the large island of Madagascar. This ammonite has been cut in half and polished to reveal the detail and beauty of the inner chambers. Ammonites started growing in the small center and added chambers spiraling outward as they grew. The living animal lived only in the last large chamber and the inner chambers were airtight and could be filled with water or air by the living ammonite using its tube-like Siphuncle to move up or down in the water.
The beautiful large 7.75 inch ammonite has inner chambers filled with various hues of colored calcite, some chambers still partially open with yellow or brown calcite crystals inside and a couple of chambers filled with gray and even red mud. The unpolished sides show interesting suture patterns as well as some of the original mother of pearl. Both halves are spectacularly displayed on a 4.5 x 5 inch black metal stand.

Original Feathered Dinosaur in Matrix. This 20 inch long important dinosaur Jeholosaurus from Central Asia is 100% real bone and is still in the same position that it died in over 125 million years ago. Jeholosaurus belongs to a little know taxa of dinosaurs know as Heterodontosauridae. These small supposedly plant eating dinosaurs are very early Ornithipods and are little understood because so few of them have been discovered. Just recently a slightly older but similar Heterodontosauridae known as Tianyulong was found in Liaoning, China as is important as it was clearly feathered with short small feathers. This means that its slightly later ancestor Jeholosaurus would also have been feathered. This is extremely important as no Ornithipod or plant eating dinosaur had ever been found that had feathers. Only some theropod, meat eating dinosaurs have been found to have feathers. Thus Jeholosaurus is a missing link animal that bridges the feather gap of Ornithipod and Theropod dinosaurs. Jehosaurus is 125-130 million years old and was found in the tuffaceous volcanic sandstone of the lower Yixian formation in Liaoning Province of Central Asia. Even the teeth of Jeholosaurus look like a cross between a meat eating and plant eating dinosaur with sharp pointed teeth in the front of the jaw and flat teeth in the rest of the jaw like a plant eating dinosaur. Perhaps they were omnivores eating both plants and insects and possibly small lizards.
This 20 inch long juvenile Jeholosaurus has been partially prepared in its original 17 x 13 inch reddish brown stone matrix keeping the dinosaur in the same curled position that it was in over 125 million years ago when it was buried in volcanic ash. The dinosaur was lying on its side with one front and one back leg exposed, the other legs are most likely still buried in the matrix. The bone quality is an excellent solid cream color which contrasts nicely with the reddish brown matrix. The front leg lies in a curled raptor-like position with one sharp claw exposed. The back leg curves into the body with one claw also visible. The all important skull has been prepared in a stunning 3-D appearance above the matrix and is excellent with almost a full set of teeth on the exposed side even with the rarely preserved sharp pointed premaxillary teeth. Several other exposed sections of bone are visible in the matrix surrounding the dinosaur. Undoubtedly, more bone is present than what has been expertly prepared. This is a rare opportunity to acquire a completely original dinosaur fossil in situ with no restoration work done to complete the specimen. Even though Jeholosaurus definitely had feathers when alive, no specimen has so far been found with any fossilized feathers.

Pair of Unhatched 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 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 museum quality pair of eggs has sharp textured fully airbrushed detail on the shell and about 90% original shell on one and 80% shell on the other egg. The shell is a dark gray color which nicely contrasts the 10.5 x 5 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. Oviraptor eggs are almost impossible to find in such pristine condition.

Trio of Dinosaur Feathers. At 125-135 million years old these three possible dinosaur feathers are some of the oldest feathers known exceeded in age only by the 150 million year old Archaeopterix bird feather from Solnhofen. The first protofeather that formed in dinosaurs was just a hollow barb made out of keratin the same protein that makes up our finger nails. The next step was the separation of the barbs into filaments forming a tassel-like feather. The largest of these feathers.8 inch long has a central barb with four different filament branchings similar to some neck or tail dinosaur feathers. The second feather is a .6 inch long most likely a body feather that has a weak center barb and small thin curved filament feathers radiating outward randomly. The third .5 inch feather has no center barb but just many thin filaments that may be head or body feathers. These feathers were found in a fossilized volcanic lake bed in Liaoning in Northeastern China, the sight where many types of feathered dinosaurs have been discovered. Although it is impossible to distinguish between bird and dinosaur feathers, the only flightless animals found in Liaoning have been dinosaurs so the probability is great that these are indeed dinosaur feathers. These valuable and well defined rare feathers are housed in a 8 x 6.5 inch Riker mount.

This lot consists of both the positive and negative slabs of Acadoparadoxites, one of the largest and one of the very earliest trilobites (over 500 million years old) 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 pygidium.

Tyrannosaurus bataar looked virtually the same as its more famous relative T-Rex but was slightly smaller in size and older in the fossil record at 70-80 million years old. Tyrannosaurus bataar may be the direct ancestor to T-Rex of which no eggs have ever been found. Tyrannosaur eggs are very rare because unlike herbivorous dinosaurs, tyrannosaurs were solitary animals that did not lay their eggs in colonies and only a single isolated nest is ever found. This rare three egg partial nest in its original 19 x 18 inch red sandstone matrix consists of one huge 16 x 5 inch complete egg and two large partials 14 x 5 inches and 11 x 5 inches. These eggs have about 80% original shell on their exposed surface and are somewhat crushed which is almost always the case because of their immense size and the thinness of their shell. This size is just about the maximum possible because any egg cannot be any thicker or it would not allow oxygen in or waste gases to escape out and the embryo would die. These immense heavy 16 inch long eggs have definitely been identified as being from a tyrannosaur as embryos have been found in a couple of them with one even having a small skull with sharp theropod teeth. These eggs are in tremendous demand because no more can be obtained from Asia and the only ones that are available have to come from existing collections.

Winged Termites and Twigs in 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. This 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 3.3 x 2.8 inch clear amber nugget weighing 562grams(over one pound). This magnificent nugget has been polished on three sides with the back left natural for effect and features dozens of scarce winged termites in a clear 5.5 x 2.8 inch window as well several twigs and dozens of wingless termites and other small insects in the interior. This rich golden amber nugget is both beautiful and massive with excellent detail of the winged termite hoard which is close to the surface and many other insects contained within.

Wooly Mammoth Hair. This large specimen of 20,000-30,000 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. Currently, there is an analysis of DNA from Mammoth hair similar to this specimen to get enough DNA to create a Wooly Mammoth by impregnating an African Elephant. 80% of the total Mammoth DNA has been collected. This specimen contains much more hair than usually offered and has premium pieces of the long thick reddish-brown hair that covered the body of the Mammoth. 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 and is housed in a 12 x 8 inch Riker Mount for display.
