“…Although many mammal fossils correspond to the Pampean region, the presence of taxa with tropical Brazilian affinities, such as the pampathere Holmesina paulacoutoi (Scillato-Yané et al, 2002, 2005 and the mustelid Pteronura brasiliensis (Prevosti and Ferrero, 2008), indicate that this region had distinct, more tropical influences as well (Noriega et al, 2004;Ferrero and Noriega, in press). In particular, the pampathere Holmesina paulacoutoi is thought to have lived in relatively humid environments and to have eaten soft vegetation, different from species of Pampatherium, which were more arid-adapted and likely consumed hard and abrasive grasses (De Iuliis et al, 2000;Scillato-Yané et al, 2005).…”

Likewise, the giant otter Pteronura brasiliensis is an indicator of tropical lentic freshwater rivers, streams, swamps and ponds, with preference for riverbanks surrounded by gallery forests or closed vegetation (Prevosti and Ferrero, 2008). Combined with the habitat preferences of living tapirs and the strictly tropical, humid environmental needs of Chelonoidis denticulata, this suggest that around 120,000 BP Entre Rios consisted of subtropical savannahs that alternated with humid forested areas along the major water courses or marshes (Ferrero and Noriega, in press).…”

“…En relación a las especies de zorros sudamericanos, al menos la mayoría de ellas se han reportado como fósiles para el Pleistoceno y Holoceno de América del Sur. Los sitios fosilíferos de mayor recurrencia corresponden principalmente al sector austral y bonaerense del área pampeana y sur de Patagonia (Berman, 1994;Hadler Rodriguez et al, 2004;Prevosti et al, 2005b;; Amorosio y Prevosti, 2008;Ramirez y Prevosti, 2014). Particularmente los géneros mejor representados corresponden a Dusicyon y Lycalopex.…”

“…En un sentido regional, la evidencia aportada a través la fauna fósil en la Mesopotamia, Uruguay y sur de Brasil planteaba, en cierto modo, un ámbito paleozoogeográfico particular y caracterizado fundamentalmente por la simpatría de taxones de una estirpe con afinidades típicamente intertropicales (Coendou magnus, Lundomys, Holmesina major, H. paulacoutoi, Hydrochoerus hydrochaeris, Neochoerus sp., Neolicaphrium recens, Nothrotheriidae indet., Pampatherium humboldtii, Protocyon troglodytes, Pteronura brasiliensis, Tapirus mesopotamicus; Lund, 1839;Edmun, 1996;Ubilla, 1996Ubilla, , 2004Ubilla et al, 2004Ubilla et al, , 2011Prevosti y Ferrero, 2008;Ferrero, 2009;Scherer et al, 2009;Góis, 2013;Kerber et al, 2014b), junto a otros de procedencia típicamente pampeana (Tonni et al, 1985;Prado y Alberdi, 1999;Carlini et al 2004). Alternativamente, recientes estudios han aportado interesantes resultados para América del Sur que mencionan la ocurrencia de asociaciones de mamíferos hacia los 22º S con afinidades intertropicales que se vinculaban, muy probablemente, con áreas de transición climática durante el Pleistoceno Tardío Guilardi et al, 2011;Castro y Langer, 2012;Silva et al, 2012).…”
