. The skull reaches a condylobasal length of 920 mm. Complete skeletons of
Embolotherium have not yet been recovered, although many postcranial elements referable to it have been collected. The postcranial skeleton of Embolotherium suggests a powerful, graviportal animal with a close resemblance to the late Eocene North American brontothere
Megacerops, which it rivaled or somewhat exceeded in size, making Embolotherium one of the largest brontotheres, if not the largest. Unlike many of the other Late Eocene brontotheres, there is no clear evidence that
Embolotherium was
sexually dimorphic. All known specimens have large rams. Therefore, coupled with the fact that the rams were hollow and fragile in comparison to the solid and sturdy horns of the North American brontotheres, such as
Megacerops, it does not seem likely that the ram served as a weapon for contests between males. Rather, it might have had a non-sexual function, such as signaling to each other. The ram may have served as a specialized
resonator for sound production. This hypothesis is suggested by the fact that the bony
nasal cavity extends to the peak of the ram, thus implying that the nasal chamber was greatly elevated, possibly creating a
resonating chamber. ==References==
