Stromaphorus is an extinct genus of Glyptodont. It lived during the Late Miocene, and its fossilized remains were discovered in South America.

Description

This animal, like all glyptodonts, had a strong carapace covering almost its entire body, consisting of numerous osteoderms fused together. The tail was protected by four rings of osteoderms, the last of which being fused with a terminal caudal tube, similar to that of Neosclerocalyptus. Unlike Neosclerocalyptus, the large lateral osteoderms covering the skull of Stromaphorus were contiguous. Its skull was narrow and elevated in the back. Its teeth were large and tall. Its feet were rather slender, with elongated metapods and phalanges.

Classification

The genus Stromaphorus was first described in 1926 by Castellanos. Two species were attributed to the genus, Stromaphorus compressidens and S. cuneiformis, both from Late Miocene Argentina.

Stromaphorus belonged to the tribe Hoplophorini, a widespread and diverse clade of glyptodonts, including genera such as Hoplophorus and Neosclerocalyptus. However, the precise phylogenetic relationships between Stromaphorus and the other members of its clade are still unclear.
