The water opossum, also locally known as the yapok, is a marsupial of the family Didelphidae. It is the only living member of its genus, Chironectes. This semiaquatic creature is found in and near freshwater streams and lakes from Mexico through Central and South America to Argentina and is the most aquatic living marsupial. It is also the only living marsupial in which both sexes have a pouch. The thylacine, commonly referred to as the Tasmanian tiger, also exhibited this trait, but it is now extinct.

Ilha Grande, or "big island", is a 193 km2 (75 sq mi) forested island located around 151 km off of the Atlantic coast of Angra dos Reis, Rio de Janeiro, Brazil, and about 450 km from São Paulo. A popular outdoor destination, the island remains largely undeveloped as much of the area falls within Ilha Grande State Park. Thus, the remainder of the island is subject to stringent development restrictions in order to preserve the natural environment; vehicles are not permitted and roads are virtually non-existent. For visitors, an hour-long, pre-paid boat excursion is the sole way to access the island. Several small villas and hamlets cater to researchers, tourists and nature-lovers, and around 2,000 people inhabit the largest town on the island, Vila do Abraão.

<i>Thylamys</i> Genus of marsupials

Thylamys is a genus of opossums in the family Didelphidae. The premaxillae are rounded rather than pointed. The females lack a pouch. The females' nipples are arranged in two symmetrical rows on the abdomen. All species but T. macrurus store fat in their tails., although this is not necessarily true for all species in the genus. Fossils belonging to the genus date back to the Miocene, with the oldest specimens being found in the Cerro Azul Formation of Argentina and the Honda Group of Colombia. Genetic studies indicate that the genus may have originated around 14 million years ago.

The common fat-tailed mouse opossum is a species of opossum in the family Didelphidae. It occurs in Argentina, Bolivia, and Paraguay in chaco and Andean foothill habitats. Its head-and-body length is about 75 to 120 mm, and its tail length is about 90 to 134 mm. Its dorsal fur is brownish gray, and its ventral fur is yellowish to white. The legs and cheeks are the same color as the ventral surface. Its tail is sharply bicolored. A ring of faintly darker fur surrounds each eye. Its tail often lacks fat deposits, but does not always.

<i>Hondadelphys</i>

Hondadelphys is an extinct genus of carnivorous sparassodonts, known from the Middle Miocene of Colombia. The type species, H. fieldsi, was described in 1976 from the fossil locality of La Venta, which hosts fossils from the Villavieja Formation. Hondadelphys was originally interpreted as belonging to the opossum family Didelphidae, but subsequently assigned to its own family, Hondadelphidae and interpreted as a basal sparassodont. The genus name refers to the Honda Group, the stratigraphic group in which the fossils of this animal were first found, combined with delphys (Greek for "womb", a common suffix used for opossum-like metatherians).

<span class="mw-page-title-main">Lapa do Santo</span> Archaeological site in Brazil

Lapa do Santo is an archaeological site located in the northern part of the Lagoa Santa karst, in the state of Minas Gerais in east-central Brazil. It documents human presence since ca. 12000 years ago presenting three discrete occupation phases that correspond to the early, middle and late Holocene. Lithic technology, zooarchaeology, and multi-isotopic analyses indicate groups of hunter gathers with low mobility and a subsistence strategy focused on gathering plant foods and hunting small and mid-sized mammals. The use of Lapa do Santo as an interment ground started between 10.3 and 10.6 cal kyBP with primary burials. Between 9.4 and 9.6 cal kyBP central elements in the treatment of the dead were tooth removal, mutilation, defleshing, exposure to fire and possibly cannibalism, all to reduce the body ahead of reburial of the remains while adhering to strict rules. In the absence of monumental architecture or grave goods, these groups were using parts of fresh corpses to elaborate their rituals. As part of this funerary agenda Lapa do Santo presents the oldest case in the New World of decapitation. Another type of burial included pits filled with separated bones of a single individuals presenting abundant evidence of perimortem fracturing. Lapa do Santo also presents a rare instance of securely dated rock art: an early Holocene low relief anthropomorphic figure depicting a phallus.
