Uruguay, officially the Oriental Republic of Uruguay, is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast, while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately 176,215 square kilometres (68,037 sq mi). It has a population of around 3.4 million, of whom nearly 2 million live in the metropolitan area of its capital and largest city, Montevideo.
Eucalyptus is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of Eucalyptus are trees, often mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts or "gum trees". Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard, or stringy, the leaves have oil glands, and the sepals and petals are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
The Uruguay national football team represents Uruguay in international men's football, and is administered by the Uruguayan Football Association, the governing body for football in Uruguay. The national team is commonly referred to as La Celeste.
Phorusrhacids, colloquially known as terror birds, are an extinct family of large carnivorous, mostly flightless birds that were among the largest apex predators in South America during the Cenozoic era. Their definitive fossil records range from the Middle Eocene to the Late Pleistocene around 43 to 0.1 million years ago, though some specimens suggest that they were present since the Early Eocene.
The Brazilian teal or Brazilian duck is the only duck in the genus Amazonetta. It is widely distributed in eastern South America.
Schinus is a genus of flowering trees and tall shrubs in the sumac family, Anacardiaceae. Members of the genus are commonly known as pepper trees. The Peruvian pepper tree is the source of the spice known as pink peppercorn.
Actinopus is a genus of mygalomorph spiders in the family Actinopodidae. It was first described by Josef Anton Maximilian Perty in 1833 from the type species Actinopus tarsalis found in Brazil. The name is derived from Greek actin- "ray, beam" and pous "foot". It is a senior synonym of Aussereria, Closterochilus, Pachyloscelis, and Theragretes.
Butia is a genus of palms in the family Arecaceae, native to the South American countries of Brazil, Paraguay, Uruguay and Argentina. Many species produce edible fruits, which are sometimes used to make alcoholic beverages and other foods. The name is derived from a Brazilian vernacular word for members of the genus.
Lundomys molitor, also known as Lund's amphibious rat or the greater marsh rat, is a semiaquatic rat species from southeastern South America.
Pholidosauridae is an extinct family of aquatic neosuchian mesoeucrocodylian crocodylomorphs. Fossils have been found in Europe, Africa, North America and South America. The pholidosaurids first appeared in the fossil record during the Bathonian stage of the Middle Jurassic. Jouve & Jalil (2020) described postcranial material of a pholidosaurid from the Paleocene (Danian) of Ouled Abdoun Basin (Morocco), representing the most recent record of the family. The authors also reinterpreted putative Maastrichtian dyrosaurid Sabinosuchus as a pholidosaurid, and argued that at least two independent pholidosaurid lineages reached the Maastrichtian, among which one survived the Cretaceous–Paleogene extinction event. Before the publication of this study it was thought that the family became extinct during the Late Turonian stage of the Late Cretaceous.
Meridiosaurus is an extinct genus of mesoeucrocodylian that is a possible member of the family Pholidosauridae. Remains have been found in the Late Jurassic Tacuarembó Formation in Tacuarembó, Uruguay. The genus was described in 1980 on the basis of a partial rostrum that included the premaxillae and most of the maxillae. The assignment to Pholidosauridae is considered doubtful by some authors, but a 2011 redescription and phylogenetic analysis confirmed the pholidosaurid classification of Meridiosaurus.
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.
Neolicaphrium is an extinct genus of ungulate mammal belonging to the extinct order Litopterna. This animal lived from the Late Pliocene (Chapadmalalan) to the Late Pleistocene (Lujanian) in southern South America, being the last survivor of the family Proterotheriidae.
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.
Fiandraia is an extinct monotypic genus of notoungulate that lived in Uruguay during the Oligocene and the Early Miocene. It was found in the Fray Bentos Formation, in rocks dated back from the Deseadan period.
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.
Eopachyrucos is an extinct genus of interatheriid notoungulates that lived from the Middle Eocene to the Late Oligocene of Argentina and Uruguay. Fossils of this genus have been found in the Sarmiento Formation of Argentina and the Fray Bentos Formation of Uruguay.
