Opossums () are members of the marsupial order Didelphimorphia () endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 126 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America in the late Cenozoic. The Virginia opossum is the only species found in the United States and Canada. It is often simply referred to as an opossum; in North America, it is commonly referred to as a possum (; sometimes rendered as 'possum in written form to indicate the dropped "o"). The Australasian arboreal marsupials of suborder Phalangeriformes are also ca…

Skeleton of an unusual, cat-sized marsupial relative (Metatheria: Marsupialiformes) from the middle Eocene (Lutetian: 44-43 million years ago) of Turkey.. We describe a near-complete, three-dimensionally preserved skeleton of a metatherian (relative of modern marsupials) from the middle Eocene (Lutetian: 44-43 million years ago) Lülük member of the Uzunçarşıdere Formation, central Turkey. With an estimated body mass of 3-4 kg, about the size of a domestic cat (Felis catus) or spotted quoll (Dasyurus maculatus), it is an order of magnitude larger than the largest fossil metatherians previously known from the Cenozoic of the northern hemisphere. This new taxon is characterised by large, broad…

New records of tick-host mammal interactions (Acari: Ixodidae) in two conservation units of the Brazilian Amazon.. Ticks are ectoparasites of major public and veterinary health importance, and identifying their vertebrate hosts is crucial for recognizing pathogen reservoirs. This study investigated tick-wild mammal associations in two areas of the Brazilian Amazon. Between 2021 and 2023, wild mammals were captured using Tomahawk® and Sherman® traps, and ticks were collected manually or with forceps. A total of 110 wild mammals were captured, including 66 marsupials, 43 rodents, and one felid, representing 12 genera. Three species were identified at the species level: Didelphis marsupialis,…

This is a list of the native wild mammal species recorded in South America. South America's terrestrial mammals fall into three distinct groups: "old-timers", African immigrants and recent North American immigrants. The marsupials and xenarthrans are "old-timers", their ancestors having been present on the continent since at least the very early Cenozoic Era. During the early Cenozoic, South America's only land connection was to Antarctica, so it was effectively cut off from most of the world; as the fragments of Gondwana continued to separate, this connection was lost, leaving South America an island continent. Caviomorph rodents and monkeys arrived as "waif dispersers" by rafting across t…

Peramelemorphia is an order of Australian marsupial mammals. Members of this order are called peramelemorphs and include bandicoots and bilbies. They are found in Australia and New Guinea, generally in forests, shrublands, grasslands, and savannas, though some species are found in inland wetlands and deserts. They range in size from the Arfak pygmy bandicoot, at 14 cm (6 in) plus a 11 cm (4 in) tail, to the giant bandicoot, at 56 cm (22 in) plus a 34 cm (13 in) tail. Peramelemorphs primarily eat insects and fruit, as well as other invertebrates and small vertebrates. Most peramelemorphs do not have population estimates, but the ones that do range from 1,000 to 100,000 mature individuals. Th…

Torquenema n. g., Wallabicola n. g., and Macropostrongyloides phascolomys n. sp.: New Genera and a New Species of Nematode (Strongylida: Phascolostrongylinae) Parasitic in Australian Macropodid and Vombatid Marsupials. The strongyloid nematodes belonging to the subfamily Phascolostrongylinae occur primarily in the large intestines of macropodid and vombatid marsupials. Current molecular evidence suggests that the two nematode species, Macropostrongyloides dissimilis and Paramacropostrongylus toraliformis, from macropodid marsupials are distant from their respective congeners. Furthermore, specimens of Macropostrongyloides lasiorhini from the large intestines of the southern hairy-nosed womb…
