The limbs are very strong, and the feet short and broad, resembling externally those of an elephant or tortois Glyptodonts constitute a family, the Glyptodontidae, whose position is next to the armadillos (Dasypodidae); the group being represented by a number of generic types.
In the early Pleistocene epoch, when South America became connected with North America, some of the glyptodonts found their way into the latter continent.
In Propalaeohoplophorus the scutes of the carapace, which are less deeply sculptured than in the larger glyptodonts, are arranged in distinct transverse rows, in three of which they partially overlap near the border of the carapace after the fashion of the armadillos.
