Resumen:
Pampatheriidae (middle Miocene-late Pleistocene) constitutes an extinct
clade of Cingulata widely dispersed in South America, entering in Central and
North America during the Great American Biotic Interchange. In the Pleistocene
of South America, two genera are recorded: Pampatherium
(with 3 species) and Holmesina (with
6 species). In the Pleistocene palaeofauna of Tarija Valley (Bolivia) one of
the most conspicuous recorded taxa are are the Cingulata, including Pampatheriidae.
Until this contribution all the remains were classified as P. typum and Pampatherium
sp. Here we present a modern taxonomic
revision of the Pampatheriidae of the Tarija Valley, based on previous
collected and published material together with new materials come from field
work carried out during 2011-2013. The
evidence indicates that a single species
of Pampatheriidae is present in the Tarija Valley (Pampatherium humboldtii), whereas the presence of P. typum
in discarded. From a chrono-stratigraphic point of view, the biochron of this
species is restricted to the late Pleistocene. This supports previous
hypothesis on the age of the sediments of Tarija Valley (Tolomosa Formation).
