RARE TYRANNOSAUR AND HADROSAUR PREDATOR AND PREY ASSOCIATED DINOSAUR TOOTH AND BONE KILL SITE FOSSIL SPECIMEN Lance Formation - Lance Creek, Wyoming, U.S.A. LATE CRETACEOUS PERIOD: 68 - 65 million years ago No dinosaur commands more respect and fascination than the members of the tyrannosaur family. Throughout the world and across a many cultures, the tyrannosaur dinosaurs are regarded without equal - true living, breathing dragons that once walked the Earth. Without question, fine quality fossils of these dinosaurs will steadily appreciate in value and price year after year as the growing number of collectors puts increasing pressure on the market supply of decreasing fine specimens for sale. The limited legal collecting regions in the United States continue to be scavenged and produce less and less high grade fossil remains with each passing year. Found in the famous Lance Formation from which this tyrannosaur was first discovered, this is very unusual original site matrix specimen that contains many fossils exactly as they were found and arranged prior to burial nearly 70 million years ago. Important as an educational piece, it displays predator and prey dinosaur fossils together. The large piece of matrix has fossils on both sides. One side shows a large distal end of a hadrosaur pubis bone. A couple of inches in the same layer further, and shown on the other side are concentrated bone fragments, turtle shell fragments and a superb and complete tooth from a Nanotyrannus lancensis, a member of the tyrannosaurid family. This is a VERY RARE specimen as it shows how concentrated a multitude of fossils can be deposited on some sites. The piece was collected in two separate sections with the main fracture running across the center. The bone has no restoration or fabrication and exhibits exceptional preservation. We left the cracks visible. All the fossils and especially the tyrannosaur tooth you see are still in their original position. This specimen was retrieved from the field in two main pieces and we reattached the two sections and filled the crack in the sand, as well as stabilized the entire matrix block. The tip of the Nanotyrannus tooth required a single fracture repair only. All work performed on this piece was done by our staff in our on-site lab. With matrix fossils often offered for sale, It is common to add additional fossils to dress up a piece for higher profits but nothing was added to this remarkable specimen. You see all that was found in its original position and the specimen required only repair. This is an extremely impressive dinosaur fossil to see in person and the surface is very detailed with a very high relief of the numerous fossils scattered in the hardened sandstone. It is one of the very few fossils we have ever handled that displays original predator / prey fossil dinosaur remains together. This spectacular piece would make a memorable exhibit to demonstrate the evidence of what a kill site would have looked like in the field without leaving the comfort of your educational institution or home. HIGHLY RECOMMENDED! Nanotyrannus lancensis was first discovered in the Lance Formation of Wyoming, U.S.A., hence the 'lancensis' name. The name 'Nanotyrannus' means "tiny tyrant" but at approximately 17 feet in length, Nanotyrannus was not exactly tiny, just small in comparison to its fellow tyrannosaurids. Its best known relative is the larger Tyrannosaurus rex. Like all tyrannosaurs, Nanotyrannus was a bi-pedal carnivore. It had narrow hips, a slim tail, long legs with three-toed feet and short arms with two-fingered hands. Its short, thick neck carried a large head with large jaws of sharp curved and serrated teeth. It is theorized that it weighed less than 1000 pounds. More than 20 Nanotyrannus teeth, one as small as 0.4 inches in length, were found scattered amongst the bones of the famous Triceratops skeleton KELSEY indicating possible multiple Nanotyrannus dinosaurs were responsible for the kill. It is theorized by some that these ferocious tyrannosaurs might have hunted in packs like dromaeosaurs.
Considerable controversy has surrounded this dinosaur in recent times. The only fossil remains are a single 22 inch skull discovered in 1942 and collected teeth. In 1988, paleontologists M. Williams, R. Bakker, and P. J. Currie examined the skull and theorized it is from a new species of tyrannosaur. Other paleontologists claim it is a juvenile T. rex. Studies are ongoing but based on indisputable evidence on the differences in structure of Tyrannosaur rex teeth and that of Nanotyrannus teeth as well as the more graceful leg bones of Nanotyrannus, it is most likely that Nanotyrannus is not only a valid species but the fastest tyrannosaur that ever lived. AMAZING PREDATOR AND PREY ASSOCIATION DINOSAUR FOSSIL NANOTYRANNUS TOOTH IS LOCATED AS FOUND ABOVE A HADROSAUR BONE IN ORIGINAL MATRIX! 14.5" x 9" overall, tooth is 1.25" long on the leading edge SOLD DBX004 INCLUDES STAND Actual Item - One Only |
