Procyonidae is a New World family of the order Carnivora. It comprises the raccoons, ringtails, cacomistles, coatis, kinkajous, olingos, and olinguitos. Procyonids inhabit a wide range of environments and are generally omnivorous.
The New World porcupines, family Erethizontidae, are large arboreal rodents, distinguished by their spiny coverings from which they take their name. They inhabit forests and wooded regions across North America, and into northern South America. Although both the New World and Old World porcupine families belong to the Hystricognathi branch of the vast order Rodentia, they are quite different and are not closely related.
Florentino Ameghino was an Argentine naturalist, paleontologist, anthropologist and zoologist, whose fossil discoveries on the Argentine Pampas, especially on Patagonia, rank with those made in the western United States during the late 19th century. Along with his two brothers –Carlos and Juan– Florentino Ameghino was one of the most important founding figures in South American paleontology.
Bauhinia forficata, commonly known as Brazilian orchid tree, pata-de-vaca,, pezuña de vaca is a species of flowering tree in the pea family, Fabaceae, that is native to Argentina, Brazil, Uruguay and Peru.
The order Pilosa is a group of placental mammals, extant today only in the Americas. It includes the anteaters and sloths, including the extinct ground sloths, which became extinct about 10,000 years ago. The name comes from the Latin word for "hairy". Pilosans are good examples of ecological harmony. Anteaters, for example, feed lightly and for a short time at any one ant nest, allowing the colony to regrow easily. Also, sloths' fur is home to many insects, as well as a type of alga that helps camouflage the sloths.
Iuticosaurus is a genus of titanosaur sauropod dinosaur from the Early Cretaceous of the Isle of Wight. Two species have been named: I. valdensis and I. lydekkeri. I. valdensis was found in the Wessex Formation and I. lydekkeri in the younger Upper Greensand.
Stegomastodon is an extinct genus of gomphotheres, a family of proboscideans. It ranged throughout North America from the early Blancan ~4 Ma, to the early Irvingtonian. The South American species have been synonymized with Notiomastodon platensis.
The Rio de Janeiro antwren is a species of bird in the family Thamnophilidae. It is endemic to Brazil, and is currently thought only to survive in Guapi Açu Ecological Reserve, although identification is tricky and its continued survival has been questioned.
The Maranhão slider, also commonly known as the Brazilian slider or Carvalho's slider, is a species of turtle in the family Emydidae.
Brassia verrucosa, also known as warty brassia, is a species of plant in the family Orchidaceae native to Mexico, Central America, Venezuela, and Brazil.
Prescottia is a genus of flowering plants from the orchid family, Orchidaceae. It is widespread across much of Latin America and the West Indies, with one species (P. oligantha) extending into Florida.
Tripogandra is a genus of flowering plants in the spiderwort family, Commelinaceae. It is native to the Western Hemisphere from central Mexico and the West Indies south to Argentina.
Inga laurina is a species of plant in the family Fabaceæ. It is found from Mexico south to Argentina. The species is present throughout most of Brazil, where it is called ingá-mirim due to the relatively small pods.
Passiflora cincinnata is a species of Passiflora from Brazil.
Passiflora membranacea is a species of Passiflora from Costa Rica, Guatemala, and El Salvador.
Neochen debilis is an extinct species of goose from the Middle Pleistocene Belgrano Formation of Argentina. Argentine paleontologist Florentino Ameghino described the species from a tarsometatarsus discovered in La Plata. It was smaller than the extant Orinoco goose.
Neochen barbadiana is an extinct species of goose from the Late Pleistocene of Barbados. The species was described by American paleontologist Pierce Brodkorb from fossils found in Ragged Point, Saint Philip. This was the third fossil species of the genus to be described, after Neochen pugil and N. debilis, from Brazil and Argentina, respectively.
Polydolopimorphia is an extinct order of metatherians, more closely related to extant marsupials than other extinct mammals. Known from the Paleocene-Pliocene of South America and the Eocene of Antarctica, they were a diverse group during the Paleogene, filling many niches, before declining and becoming extinct at the end of the Neogene. It is divided into two suborders, Bonapartheriiformes, and Polydolopiformes
Libellula herculea is a species of Libellula found in Argentina, Bolivia, Brazil, Belize, Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Peru, Paraguay, El Salvador, and Venezuela
