Resumen:

On the southwestern coast of Uruguay, in the Colonia and San José departments, sedimentary rocks that correspond to the Neogene and Quaternary are found. Herein we describe the fossiliferous locality of Santa Regina, located on the east coast of the department of Colonia. The stratigraphic profile shows at the base grayish-green sandy rocks belonging to the Camacho Formation (Upper Miocene). Overlying this unit, there is a tough yellowish-greenish siltstone in net contact, in which several pieces of a Notiomastodon platensis specimen were found. Towards the upper part, a thicker greenish-brownish bed is observed, ranging upwards from conglomerates to siltstones. The lower part of this bed includes disarticulated and fragmentary remains of Lestodon armatus, Glyptodon reticulatus, Pampatheriidae indet., Toxodon cf. T. platensis, Morenelaphus sp., and Lycalopex gymnocercus, and to the top large portions of carapaces of Glyptodon sp. and Panochthus sp. The aforementioned mastofaunistic assemblage corresponds to the Lujanian Mammal Age or regional Stage (Upper Pleistocene-Greenlandian). The lithostratigraphy allows us to refer the two upper levels to the Dolores Formation, a characteristic unit of the Quaternary of southern Uruguay, and not to the Raigón Formation, as indicated in some previous reports for this locality. The presence of Lestodon armatus, Glyptodon reticulatus, Notiomastodon platensis, Lycalopex gymnocercus, and the probable presence of Toxodon platensis, allow us to infer landscapes of open or semi-open areas, with a predominance of grasslands and shrubs during the genesis of the deposits.


Na zona costeira do sudoeste do Uruguai, nos departamentos de Colônia e San José, afloram rochas sedimentares correspondentes aos sistemas Neógeno e Quaternário. Descrevemos aqui o sítio fossilífero de Santa Regina localizado na costa leste do Departamento de Colônia. O perfil estratigráfico está composto na base por rochas arenosas verde-acinzentadas pertencentes à Formação Camacho (Mioceno Superior). Sobreposto a esta unidade, em contato de rede, ocorre um siltito amarelo-esverdeado tenaz, no qual foram encontradas várias peças de um exemplar de Notiomastodon platensis. Em direção à parte superior observa-se um nível mais espesso verde-acastanhado, com grãos diminuindo de conglomerados para siltitos. Este nível inclui na parte basal restos desarticulados e fragmentados de Lestodon armatus, Glyptodon reticulatus, Pampatheriidae indet., Toxodon cf. T. platensis, Morenelaphus sp., e Lycalopex gymnocercus, e mais acima grandes porções de couraças de Glyptodon sp. e Panochthus sp. O conjunto mastofaunístico mencionado se corresponde com a Idade Mamífero Piso/Idade regional Lujanense (Pleistoceno Superior-Groenlandiense). A litoestratigrafia permite referir aos dois níveis superiores descritos à Formação Dolores, unidade característica do Quaternário do sul do Uruguai, e não à Formação Raigón, como fora assinalado em alguns trabalhos prévios para a localidade em questão. A presença de Lestodon armatus, Glyptodon reticulatus, Notiomastodon platensis, Lycalopex gymnocercus e a provável presença de Toxodon platensis, permitem inferir paisagens de áreas abertas ou semiabertas, com predomínio de pastagens e arbustos, durante a gênese dos depósitos.
