The Dromomerycids were a family of deer/antelope-like ruminates that lived during the Miocene... I think the majority of them were native to North America.
The three-horned monster is Procranioceras skinneri, while the four-horned beast behind it is Sinclairomeryx riparius. The small, ring-horned buck is Rakomeryx sinclairi.
