Photo of a skeleton recovered from the La Brea Asphalt Pits Breameryx Capromeryx (dwarf pronghorn) is an extinct genus of dwarf pronghorns (Antilocapridae) that originated in North America during the Pliocene about 5 million years ago (the exact range of their presence on the landscape is still not known, but the most recent fossils found are dated to 11,000 years ago).

One such location is the Rancho La Brea Tar Pits in Los Angeles, where enough bones have been unearthed to produce a full skeleton sample of Capromeryx minor.

[3] Much like the living pronghorns that exist today, the habitat that these animals were thought to inhabit were grassy plains with some shrubs and large trees for them to take refuge in.

[1] It is still unknown what exactly they ate and how they interacted socially but it is speculated that they were similar in many ways to their living relatives, the North American Pronghorn.

[5] Fossils identified as the family Antilocapridae are similarly distributed into genus by size, with Capromeryx being the smallest of the known Pronghorns.

They discovered the fossils that included horn cores and teeth during a dig (from 1988 to 1992) in Blancan sediments in Adams County, Washington.
