Glyptotherium sp.—GlyptodontsRegional Pleistocene distribution of Glyptotherium sp.

Although Mead et al. (2007) listed Sonoran species as Glyptotherium cylindricum, evidence was not strong and White et al. (2010) reverted to Glyptotherium sp. the Sonoran localities listed below.

Sites.

Late Blancan: San Simon Fauna (Morgan and White 2005).

Rancholabrean: Chinobampo (White et al. 2010); La Botana (White et al. 2010); Llano Prieto (White et al. 2010).

Glyptotherium arizonae Gidley 1926—Gidley's GlyptodontPleistocene distribution of Glyptotherium arizonae

Three articulated glyptodont scutes and edge view of anotherGlyptodonts are large, armored relatives of the armadillos. Individual scutes of the armor, and occasional articulated portions, are found from the Blancan to Irvingtonian deposits along the Rio Grande Rift. Morgan and Lucas (2005), based on the revision of the genus by Gillette and Ray (1981), assigned all New Mexican glyptodonts to G. arizonae; the Arizona specimens likewise are of this species.
