S. magellanicus (Aves, Sphenisciformes). This finding, located within the current migratory route of the species, potentially constitutes the northernmost fossil record of S. magellanicus, and the first report of a fossil penguin from Uruguay. Briefly comments about the features supporting its systematic, ontogenetic, and taphonomic assignment are also given.

La presencia del yaguarundí, Herpailurus yagouaroundi (É.Geo roy Saint-Hilaire, 1803) en Uruguay ha sido controversial. Sistematizamos sus registros y analizamos menciones históricas y recientes. Existen varios reportes en los siglos XIX y XX, aunque sin evidencia material. Eso llevó a excluirlo de la mastofauna uruguaya entre 1972 y 2016, año este último en que fue documentado mediante cámaras trampa. La información nacional y regional sugiere que, en la actualidad y probablemente en el pasado, se han registrado en Uruguay dos morfos de pelaje (oscuro y rojizo). Sería una especie escasa y posiblemente amenazada y se necesitan más estudios para determinar su estado de conservación en el país. ABSTRACT. The jaguarondi, Herpailurus yagouaroundi (Carnivora: Felidae) in Uruguay: historical account and current situation. The presence of the jaguarondi, Herpailurus yagouaroundi (É. Geo roy Saint-Hilaire, 1803) in Uruguay has been controversial. We systematized its records and analyzed historical and current mentions. There have been reports in the 19 th and 20 th centuries, although without material evidence. This led to the species not being considered among the native fauna between 1972 and 2016 when it was nally documented with camera traps. The information at national and regional levels suggests that currently and probably in the recent past, two pelage variants (grey and reddish) were recorded in Uruguay. Albeit it is scarce and possibly endangered in Uruguay, more studies are needed to assess the conservation status in the country.

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 Lestodonarmatus, Glyptodon reticulatus, Pampatheriidae indet., Toxodon cf. T. platensis, Morenelaphus sp., and Lycalopex gymnocercus,...

A complex fossil association from the San Pedro Member of the Camacho Formation (late Miocene) in Puerto Arazatí, San José department, southern Uruguay, is documented in this paper. Situated at the base of the coastal cliffs, this association is characterized by many land mammals, trace fossils indicative of the Psilonichnus Ichnofacies, and irregularly distributed oyster bioherms. The trace fossils are interpreted as crab galleries, which represent a clear marginal, or even intertidal to supratidal episode within the overall marine environment recognized for the Camacho Formation. Episodic subaerial exposure of the deposits under consideration is inferred by the presence of the Psilonichnus Ichnofacies and a set of trace fossils assigned to sarcosaprophagous insects, found in the skeleton of some specimens of glyptodonts. Finally, a review of the mastofauna and the mollusks from the main localities of the San Pedro Member was conducted. This study permits redefining the biostratigraphy of this unit and confirms its late Miocene age.

It closely resembles Gnathosaurus in the orientation of the teeth and the presence of interalveolar concavities. However, a unique combination of synapomorphies distinguishes it from other members of the Ctenochasmatidae. These include the presence of a spoon-shaped spatula not sharply demarcated from the post-spatula rostrum, teeth set in alveoli with raised alveolar borders and deep interalveolar concavities, teeth both anteriorly (i.e. procumbent) and laterally oriented, tooth density of 1.58–2 teeth/cm, tooth separation subequal to tooth size, absence of dorsal concavity, presence of a conspicuous system of vessels and foramina at least in the ventral part of the snout, teeth with veined sub millimetric texture of the enamel and unconspicuous carinae. In a phylogenetic a...

lated and completely striated teeth, as well as a rostrum fragment of the pholidosaurid Meridiosaurus vallisparadisi. The
latter was found in the late 1970s in Los Rosanos town. We communicate herein the discovery of a skull fragment from the
same locality, which far decades was mixed with coelacanth bones
