Protoglyptodon is an extinct genus of glyptodont. It lived during the Late Miocene, and its fossilized remains were found in South America.
Description
[edit]This animal, like all glyptodonts, had a dorsal armor protecting a large part of the body, consisting of well-fused polygonal osteoderms. The osteoderms were quite similar to those of Palaeohoplophorus, with a medium-sized, depressed central figure, and with wrinkled and irregular peripheral areas. Its carapace appearance was more irregular in Protoglyptodon. Its caudal tube bore osteoderms whose main figures were surrounded by a crown of perforations, but separated by peripheral areas decorated in a very irregular way.
Classification
[edit]Protoglyptodon primiformis was first described in 1885 by Florentino Ameghino, based on incomplete fossil remains coming from Late Miocene terrains of Argentina, first erroneously attributed to the Oligocene. Protoglyptodon was a member of the tribe Hoplophorini, a diverse and long-lived group of glyptodonts ; Protoglyptodon was closely related to the better known genus Palaehoplophorus.
