Life restoration of Brachycrus laticeps by Robert Bruce Horsfall
The 1 metre (3.3 ft) long creature resembled its bigger, earlier relative Merycoidodon, but was more specialized. Brachycrus had jaws which were short, and because the nostrils were placed far to the back, the creature is presumed to have had a tapir-like proboscis. The positioning of the eyes on the skull and the tubular ear structure hints that Brahycrus lived a semi-aquatic lifestyle.
Dental mesowear shows that B. laticeps had a browsing diet during the late Hemingfordian, but that its diet shifted towards a more mixed feeding diet during the early Barstovian.
