Paleobiogeography of the late Pleistocene pampatheres of South America

“…In turn, Edmund (1996) suggested the putative cospecificity of H. majus and H. paulacoutoi. We believe that the comparison of both holotypes (Winge, 1915;Cartelle Guerra and Bohorquez Mahecha, 1985) supports two valid species; to the differences observed in the morphology of the carapace scutes, it may be added, for example, that the first upper molars are strongly imbricate in H. paulacoutoi but not in H. majus, which represents an unlikely intrapopulation variation.…”

“…Despite recent efforts by Cartelle Guerra and Bohorquez Mahecha (1985), Edmund (1985Edmund ( , 1987Edmund ( , 1996, and Cartelle Guerra (1999), there is still much work to do regarding the systematics of the Quaternary pampatheres of South America, their origin, and their evolutionary history. Edmund (1996) pampatheres revision clarified the validity of the two Quaternary genera Holmesina and Pampatherium, as well as the general characters of the osteoderms that allow distinguishing, for South America, three species for the first genus and two species for the latter.…”

“…paulacoutoi (Cartelle Guerra and Bohorquez Mahecha, 1985) is the most robust Pampatheriidae. This species was described on the basis of Late Pleistocene-Holocene remains from the caves of Bahía, Brazil (Fig.…”

“…With the status of Machlydotherium in question, the oldest record of an undoubted pampathere is Scirrotherium Edmund and Theodor, 1997, from the middle Miocene of La Venta, Colombia. The pampatheres, or giant armadillos, are recorded in South America up to the Late Pleistocene or perhaps even into the early Holocene (Cartelle Guerra and Bohorquez Mahecha, 1985) and entered North America as immigrants during the Great American Biotic Interchange (Stehli and Webb, 1985). Pampatheres are recorded in North America beginning in the Late Blancan (Late pliocene) until the Rancholabrean (Late Pleistocene) (Edmund, 1996).…”

Mamíferos del pleistoceno superior de santiago del estero (Argentina) y sus afinidades paleobiogeográficas

“…Comentarios: El material aquí registrado es referible a Holmesina y se distingue de Pampatherium por presentar una figura central bien definida y un área marginal deprimida y rugosa (Scillato-Yané, 1982; Scillato- . Más aún, el ejemplar puede ser referido a la especie H. paulacoutoi (Cartelle Guerra & Bohórquez Mahecha, 1985) por poseer placas de gran tamaño, de superficie muy rugosa, el área marginal amplia y baja, rodeando un área central elevada, la cual se continúa hacia atrás conformando un marcado abultamiento posterior (Scillato-Yané et al, 2005).…”
