“…Moreover, those two specimens belong to the same individual since their mandibular symphysis articulates perfectly (Rodrigues et al 2014). All previous fossil records of G. cuja are within its extant geographic distribution.…”

The evolutionary history of the genus Galictis in South America probably begins after the Great American Biotic Interchange. Two species are recognised: Galictis vittata and Galictis cuja. The latter are more frequently found in open areas in southern South America and the first occurs in humid forests from northern South America to Central America. Apparently, they do not occur in sympatry. Both are differentiate by the presence of a metaconid in the first inferior molar of G. vittata and for its bigger size when compared to G. cuja. The fossil record of Galictis is scarce, G. cuja is known by few specimens from Argentina, Chile and Brazil; G. vittata have only one record from Southern Brazil. The specimens related to this record were collected by Peter Lund and are housed at the Statens Naturhistoriske Museum. However, the specimens published by Lund are not fossils. Thus, it is presented here other unpublished specimens collected by Lund and housed at the same museum that we recognise as the first G. vittata fossils. Additionally, it is described here the first fossil record for G. cuja from the late Pleistocene of Brazil -an almost complete mandible recovered from sedimentary deposits from Central Brazil.

“…Three species from Gruta do Urso, Catagonus stenocephalus (Lund in Reinhardt, 1880), Equus neogeus Lund, 1840 and Propraopus sulcatus (Lund 1838), may suggest an open and dry environment for the region during the Late Pleistocene Castro et al, 2013;Rodrigues et al, 2014). The paleoecological implications of the vertebrate record from Gruta do Urso cave remains unclear.…”

-Here we present teiid lizard fossils from Gruta do Urso, Aurora do Tocantins, Tocantins State, northern Brazil. We describe a left lower jaw of a "Cnemidophorinae" indet. and a right dentary attributed to Tupinambis sp. These materials share with extant Teiidae a heterodont dentition with subpleurodont tooth implantation, and are assigned to Teiinae and Tupinambinae based on dental characteristics. The paleofaunal assemblage from Gruta do Urso suggests a late Pleistocene/ early Holocene age. These records add to our knowledge of the Quaternary fauna of northern Brazil.Key words: Teiidae, lizards, Quaternary, caves, Northern Brazil.RESUMO -Neste trabalho apresentamos restos fósseis de lagartos teídeos provenientes da Gruta do Urso, Aurora do Tocantins, Estado do Tocantins, norte do Brasil. Descrevem-se aqui uma mandíbula esquerda atribuída a um "Cnemidophorinae" indet.; e um dentário direito atribuído a Tupinambis sp. Estes materiais compartilham com os Teiidae uma dentição heterodonte exibindo uma implantação dentária subpleurodonte, sendo estes fósseis atribuídos aos Teiinae e Tupibaminae, respectivamente, devido ao padrão da morfologia dentária observada nestes dois grupo de lagartos. A assembleia paleofaunística da Gruta do Urso sugere uma idade do Neopleistoceno/Eoholoceno. Estes registros contribuem com o conhecimento da fauna Quaternária da região do Norte do Brasil.

Echimyidae (spiny rats, tree rats and the coypu) is the most diverse family of extant South American hystricognath rodents (caviomorphs). Today, they live in tropical forests (Amazonian, coastal and Andean forests), occasionally in more open xeric habitats in the Cerrado and Caatinga of northern South America, and open areas across the southern portion of the continent (Myocastor). The Quaternary fossil record of this family remains poorly studied. Here, we describe the fossil echimyids found in karst deposits from southern Tocantins, northern Brazil. The analyzed specimens are assigned to Thrichomys sp., Makalata cf. didelphoides and Proechimys sp. This is the first time that a fossil of Makalata is reported. The Pleistocene record of echimyids from this area is represented by fragmentary remains, which hinders their determination at specific levels. The data reported here contributes to the understanding of the ancient diversity of rodents of this region, evidenced until now in other groups, such as the artiodactyls, cingulates, carnivores, marsupials, and squamate reptiles.
