The San Gregorio Formation is an Asselian geologic formation in Uruguay. [1]
The following fossils have been reported from the formation:
Scarrittia is an extinct genus of hoofed mammal of the family Leontiniidae, native to South America during the Late Oligocene epoch.
The Waldensian Evangelical Church is a Protestant denomination active in Italy and Switzerland that was independent until it united with the Methodist Evangelical Church in Italy in the Union of Methodist and Waldensian Churches. Founded in the 12th century by Peter Waldo as a proto-Protestant group, since the 16th century Reformation it has adopted Calvinist theology and blended into the wider Calvinist tradition. It is one of several Protestant denominations with pre-Reformation roots, and is appraised by various denominations of Protestantism as its major successor.
Josephoartigasia is an extinct genus of enormous dinomyid rodent from the Early Pliocene to Early Pleistocene of Uruguay. The only living member of Dinomyidae is the pacarana. Josephoartigasia is named after Uruguayan national hero José Artigas. It contains two species: J. magna, described in 1966 based on a left mandible, and J. monesi, described in 2008 based on a practically complete skull. Both are reported from the San José Member of the Raigón Formation by the Barrancas de San Gregorio along the shores of Kiyú beach.
The Asencio Formation is a geological formation in the Paraná Basin of southwestern Uruguay whose strata date back to the Late Cretaceous (Campanian-Maastrichtian). Dinosaur remains are among the fossils that have been recovered from the formation.
The South American land mammal ages (SALMA) establish a geologic timescale for prehistoric South American fauna beginning 64.5 Ma during the Paleocene and continuing through to the Late Pleistocene. These periods are referred to as ages, stages, or intervals and were established using geographic place names where fossil materials where obtained.
The Huayquerian age is a period of geologic time within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification. It follows the Chasicoan and precedes the Montehermosan age.
The Uruguay men's national water polo team is the representative for Uruguay in international men's water polo.
Lestobradys is an extinct genus of ground sloth, which existed in Uruguay during the Late Miocene period; Huayquerian in the South American land mammal age (SALMA). The type species is L. sprechmanni, found in the Camacho Formation of Uruguay.
Uruyiella is an extinct genus of laidleriid temnospondyl from Late Triassic Buena Vista Formation of Uruguay. It was first named by Graciela Piñeiro, Claudia Marsicano and Nora Lorenzo in 2007, from a nearly complete skull. The type species is Uruyiella liminea and it is the only close relative of the enigmatic Early Triassic Laidleria.
Pronothrotherium is an extinct genus of ground sloths from Argentina and Uruguay. Fossils of Pronothrotherium have been found in the Ituzaingó Formation of Argentina. The body weight of the animal has been estimated at 937 kg (2,066 lb).
Russian Uruguayans are people born in Russia who live in Uruguay or Uruguay-born people of Russian descent. They are a local ethnic minority.
Prohegetotherium is an extinct genus of hegetotheriid notoungulates from the Late Oligocene to Early Miocene of the Agua de la Piedra, Mariño & Sarmiento Formations of Argentina, the Petaca and Salla Formations of Bolivia, and Fray Bentos Formation of Uruguay.
Tacuarembemys is an extinct genus of continental turtle from South America. It contains a single species, T. kusterae. The genus was described based on the external mold of a carapace and associated shell bone fragments found near the city of Tacuarembó, Uruguay. This fossil was found on the Tacuarembó Formation, whose estimated age ranges from late Jurassic to earliest Cretaceous.
Charruatoxodon is an extinct monotypic genus of notoungulate belonging to the family Toxodontidae. It lived from the Pliocene to the Early Pleistocene in what is now southern Uruguay. Its remains have been found in the San José member of the Raigón Formation, near Montevideo.
Uruguayodon is an extinct genus of proterotheriid from the middle Pleistocene of Uruguay. It is known from the type and only species U. alius, named by Corona and colleagues in 2019 for dentaries and a partial postcrania from the Raigón Formation. Uruguayodon represents one of the latest occurrences of Proterotheriidae, with only Neolicaphrium representing other remains from the Pleistocene to possibly Holocene.
Pseudobrachytherium is an extinct genus of proterotheriid from the Late Miocene of Uruguay. It is only known from the type species P. breve, named in 2020 by Corona and colleagues for an almost complete skull found in the greenish pelite of the San Pedro member of the Camacho Formation, which is Huayquerian in age. The genus name is derived from the similarity to the proterotheriid Brachytherium at first glance, with the species name from the Latin for "short", referencing the short groove on the rear of the second molars.
The Libertad Formation is a Lujanian geologic formation in Uruguay.
The Raigón Formation is a Huayquerian-Montehermosan geologic formation in Uruguay.
The Camacho Formation is a Huayquerian geologic formation in Uruguay.
