Asmodeus is an extinct genus of mammal, belonging to the order Notoungulata. It lived during the Late Oligocene, in what is today South America.
Description
This animal was relatively heavy-shaped, with long, strong and slender limbs. Its hand had four fingers, and a reduced fifth metacarpal. The main characteristic of Asmodeus, which shows its affinities with its relative Homalodotherium, is in the shape of its forelimbs, which made the hind legs lower than the forelegs. The front legs were clawed, and not hooved as in most of the known toxodonts. Compared to Homalodotherium, the reduction of the fifth metacarpal was less important in Asmodeus.
Classification
First described in 1894 by Florentino Ameghino, Asmodeus belonged to the family Homalodotheriidae, a group of notoungulates with characteristically elongated and clawed front legs. Two species of Asmodeus are known, including A. osborni, the type species, from the Deseado Formation of Argentine Patagonia, and A. petrasnerus from the Agua de la Piedra Formation in the Mendoza Province of Northern Argentina. The species are mainly distinguished by characteristics of the talus and the calcaneus.
