With some individuals reaching high at the shoulder and a weight of ,
Ancylotherium was relatively large, and was built rather like a
goat. Individuals varied considerably in size, and the genus may have been
sexually dimorphic, like many other chalicotheres. While it had the typical long forelimbs and short hind limbs of a chalicothere, like other schizotheriines, it did not walk on its knuckles. It was similar to the
North American genus
Moropus. In at least some individuals of
A. pentelicum the frontal bone of the skull is inflated to form a dome, similar to but less marked than in the "dome-headed" chalicothere
Tylocephalonyx. This genus is North American and
Ancylotherium is likely to be more closely related to other African and European genera, so the feature may have evolved independently in two lineages. This would suggest it reflects a common behavior in schizotheriine chalicotheres, such as using the head as a battering ram in territorial or dominance contests, as modern
giraffes do. one skull discovered in China was from a dry steppe zone with few trees; the genus may have been less dependent on browsing leaves than other chalicotheres. ==Paleoenvironment==
