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.
