The sabre-toothed cat Smilodon fatalis (Leidy, 1868) was an iconic predator in the Americas during the Ice Age. While its distribution in North America is abundant, its record in South America is very scarce and is restricted to only a few locations. In the present contribution a new skull assigned to Smilodon fatalis is described. The specimen com...

Supernumerary teeth are an uncommon feature in wild mammalian carnivores. We report a Leopardus pardalis specimen with a well-developed second lower molar in both mandibular rami. This is the first record of this tooth in this taxon, for both living and fossil specimens. The biological and evolutionary implications are discussed in addition to comp...

New findings from the Camacho Formation (Late Miocene) of Uruguay are described, most of them coming from the easternmost outcrops of this unit placed in Arazatí Harbour, San Jos´ e department. Among these remains stand out fishes: Otodus megalodon, Charcharodon plicatilis, Myliobatidae indet., and Siluriformes indet.; turtles: Phrynops sp., Chelon...

En Uruguay el jaguar, Panthera onca, se considera extinto desde 1901. Existen registros paleontológicos, arqueológicos y documentación histórica que dan cuenta de la presencia de la especie en distintas partes del territorio nacional. Asimismo, hay en el país numerosos accidentes geográficos que incluyen en su nombre la palabra “tigre”, que es como...

Felidae entered South America from North America during the Ensenadan Stage/Age (Early to Middle Pleistocene). For Uruguay their fossil record is scarce but informative, although mostly correspond to large felids (Smilodon, Panthera onca). In this work describes fossil remain of a skull and a mandible assigned, based on morphology and statistical a...

Felids are the top predators in the environments they inhabit. They entered South America at the Pliocene-Pleistocene boundary, but their fossil record in Uruguay, although informative, is scarce. In the present contribution, three new materials (two hemimandibles and an isolated first lower molar) assigned to Panthera onca (Linnaeus, 1758) are des...

A Lujanian Local Fauna (Upper Pleistocene–Lower Holocene) from southern Uruguay: Santa Regina, Colonia Department. 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 eas...
Article
The Felidae entered South America from North America during the Ensenadan Stage/Age (early to middle Pleistocene). For Uruguay, their fossil record is scarce but informative, although mostly of them correspond to large size felids (Smilodon, Panthera onca). In the present contribution, skull and mandibular remains are assigned, based on anatomical...

The association of vertebrate remains and invertebrate traces, although less studied than other bioerosion traces, provides important paleoecological information. This report describes Cubiculum ornatum Roberts, Rogers, and Foreman 2007, Osteocallis Roberts, Rogers, and Foreman 2007 and other unidentified insect traces from the dermal skeletal rema...
Article
Among the three recognized species of Smilodon, S. populator is the largest in size and has the widest distribution across South America. The present contribution describes an almost complete skull assigned to the aforementioned felid. The material was recovered from sediments of the Dolores Formation (Lujanian Stage/Age) from the southern part of...

Full-text available
The fossil record of carnivorous mammals in Uruguay is scarce and fragmentary, but informative. In the present contribution, two new records of canids allocated in sediments of the Dolores Formation (late Pleistocene-early Holocene) are described. These records, based on their anatomical-comparative study and multivariate analysis, correspond to tw...
