Chalicotheres

At the deeper end of the waterhole, where a steep bank about three feet high bordered thick deposits of undisturbed bones, about twenty chalicotheres were excavated by the American Museum of Natural History. Juveniles, young adults, older females, and large adult males were found together at the waterhole’s edge, some largely intact, suggesting a small herd that died there at one time. By contrast, bones at the periphery of the waterhole lay in a single layer and were widely scattered by scavenging animals. The chalicothere Moropus was a plant-eating animal that stood nearly seven feet tall at the shoulder and had claw-like hooves.
