    EXCEPTIONAL NEW ORNITHOPOD DINOSAUR
    Jeholosaurus shangyuanensis
    Lower Cretaceous
    Yixian Formation, Central Asia

    First discovered less than ten years ago, the Jeholosaurus was a chicken-sized Ornithopod whose exact place in dinosaur taxonomy is still the subject of research. Its skeleton indicates immediately that it must have been a fast and agile runner, useful as its small size would have made it a delectable snack for the contemporary carnivorous therapods such as the dromeosaurids and early tyrannosaurids. It is suspected to be a close relative of the Heterodontosaurus whose name refers to the different types of teeth found in the jaw; the Jeholosaurus shares this characteristic, with flattened back teeth for masticating plant material and sharp and pointed premaxillary teeth at the front, more suited to a carnivorous diet. The overall suggestion is that Jeholosaurus was an omnivore, eating insects and possibly small lizards as well as plants. The present specimen is of exceptional quality, with over 80% original bone and virtually no distortion, more complete and of even better quality than the holotype. Excavated from the tuffaceous sandstone of the Yixian formation created by a massive volcanic eruption some 130 million years ago, it has lovely bone texture and patina; superbly prepared in a straight-spined, running pose with both forearms outstretched it measures 26 inches long and stands 11 inches high on an oak base. A superb specimen only enhanced by its rarity and absence from most museum collections.


    Estimate: $24,000 - $35,000.
