Brachycrus is an extinct genus of oreodont, of the family Merycoidodontidae, endemic to North America. They lived during the Middle Miocene, 16.0—13.6 mya, existing for approximately 2.4 million years.[1]
Description
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.[2]
Palaeoecology
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.[3]
