Proterotheriidae and Macraucheniidae (Litopterna, Mammalia) from the Pleistocene of Rio Grande do Sul State, Brazil

Abstract

New materials of the order Litopterna from the late Pleistocene (Lujanian) of Rio Grande do Sul State are presented here. The specimens are an astragalus and calcaneum, assigned to cf. Neolicaphrium recens, and fragments of mandible, humeri, tibia and fibula, astragali, besides vertebrae and metatarsal, all of them attributed to Macrauchenia patachonica. The material described here comes from the municipalities of Santa Vitoria do Palmar (Hermenegildo Beach, Chui Creek), Uruguaiana (Touro Passo Creek), Alegrete (Sanga da Cruz Creek) and Pantano Grande (Sanga Borba Creek). The record of these taxa in the Lujanian of Rio Grande do Sul State shows a greater similarity with the fauna in the same latitudinal belt of Argentina and Uruguay than that of the intertropical region. RESUMO - Sao aqui apresentados novos materiais da Ordem Litopterna para o Pleistoceno final (Lujanense) do Estado do Rio Grande do Sul. Os especimes constam de astragalo e calcâneo, atribuidos a cf. Neolicaphrium recens; e fragmentos de mandibula, umeros, tibia e fibula, astragalos, alem de vertebras e metatarsal, todos atribuidos a Macrauchenia patachonica. O material aqui descrito provem dos municipios de Santa Vitoria do Palmar (Balneario Hermenegildo e Arroio Chui), Uruguaiana (Arroio Touro Passo), Alegrete (Sanga da Cruz) e Pantano Grande (Sanga Borba). O registro destes taxons para o Lujanense do RS evidencia, mais uma vez, a maior similaridade da fauna deste estado com a da mesma faixa latitudinal da Argentina e do Uruguai, do que com a da regiao intertropical.
