Its type locality is East of Hyde Post-office, which is in a Barstovian terrestrial shale/conglomerate in Montana.

It was recombined as Alticamelus elrodi by Stirton (1929), McGrew (1938) and Gregory (1942); it was recombined as Aepycamelus elrodi by Webb (1969), Honey et al. (1998) and Tabrum and Nichols (2001).

Diagnosis
ReferenceDiagnosis
E. Douglass 1909
The species is distinguished by its large size, the pit into which the infraorbital foramen opens and the much larger pit above it, the heavy but not deep mandible, the prominence of the posterosuperior portion of the angle and the relative proportions of the cervicals which decrease in the length of the centra from the axis backwards.
