Agate in Sioux County, Nebraska — The American Midwest (Upper Plains)
Chalicotheres
Juveniles, young adults, older females, and large adult males were discovered together at this edge of the waterhole, some largely intact, suggesting a small herd that died at the waterhole at one time. Bones at the periphery of the waterhole, on the other hand, were found in a single layer and were widely scattered by scavenging animals.
