       Brontotherium like with many other ancient animals such as Paraceratherium has undergone a lot of controversial reclassification with many palaeontologists considering it a species of Megacerops.‭ ‬Although this is not universally accepted,‭ ‬the two genera are very close to one another in form,‭ ‬and both have a Y-shaped nasal horn that most probably served as a display feature.‭ ‬Many Brontotherium individuals have been found in deposits of volcanic ash which not only indicates that the area they lived in was geologically active,‭ ‬but that these mammals lived in groups.
       Brontotherium is the type genus of the Brontotheriidae,‭ ‬and like other members of this group of mammals they resembled modern rhinos in both form and ecological niche.‭ ‬Like in some related mammals,‭ ‬Brontotherium had greatly enlarged neural spines rising up from the forward dorsal vertebrae which served as attachment points for the powerful neck muscles that supported the head.‭ ‬Remains of these beasts have also been identified as the thunder horses that exist in Native American culture.
