Thylacinus is a genus of extinct carnivorous marsupials from the order Dasyuromorphia. The only recent member was the thylacine (Thylacinus cynocephalus), commonly also known as the Tasmanian tiger or Tasmanian wolf. The last known Tasmanian tiger was in the Beaumaris Zoo in Tasmania, eventually passing away in 1936. Alleged sightings of the tiger were reported after its extinction, however, no photographs or physical proof have been found to support the claims. In the first half of the 20th century, an already dwindling thylacine population was exposed to a combination of excessive hunting by humans, as well as likely competition with introduced dogs. Other prehistoric species are known from this genus. An unidentified species is known from Pleistocene New Guinea. Thylacines emerged around four million years ago and were known to inhabit Australia before they disappeared, most likely due to competition with dingos. Their last known stronghold was in Tasmania before they became extinct due to European hunting.

The thylacine, also commonly known as the Tasmanian tiger or Tasmanian wolf, is an extinct carnivorous marsupial that was native to the Australian mainland and the islands of Tasmania and New Guinea. The thylacine died out on New Guinea and mainland Australia around 3,600-3,200 years ago, prior to the arrival of Europeans, possibly because of the introduction of the dingo, whose earliest record dates to around the same time, but which never reached Tasmania. Prior to European settlement, around 5,000 remained in the wild on Tasmania. Beginning in the nineteenth century, they were perceived as a threat to the livestock of farmers and bounty hunting was introduced. The last known of its species died in 1936 at Hobart Zoo in Tasmania. The thylacine is widespread in popular culture and is a cultural icon in Australia.

Dasyuromorphia is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the extinct thylacine. In Australia, the exceptions include the omnivorous bandicoots and the marsupial moles. Numerous South American species of marsupials are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta.

Riversleigh World Heritage Area is Australia's most famous fossil location, recognised for the series of well preserved fossils deposited from the Late Oligocene to more recent geological periods. The fossiliferous limestone system is located near the Gregory River in the north-west of Queensland, an environment that was once a very wet rainforest that became more arid as the Gondwanan land masses separated and the Australian continent moved north. The approximately 100 square kilometres (39 sq mi) area has fossil remains of ancient mammals, birds, and reptiles of the Oligocene and Miocene ages, many of which were discovered and are only known from the Riversleigh area; the species that have occurred there are known as the Riversleigh fauna.

<span class="mw-page-title-main">Sparassodonta</span> Extinct order of mammals

Sparassodonta is an extinct order of carnivorous metatherian mammals native to South America, related to modern marsupials. They were once considered to be true marsupials, but are now thought to be a separate side branch that split before the last common ancestor of all modern marsupials. A number of these mammalian predators closely resemble placental predators that evolved separately on other continents, and are cited frequently as examples of convergent evolution. They were first described by Florentino Ameghino, from fossils found in the Santa Cruz beds of Patagonia. Sparassodonts were present throughout South America's long period of "splendid isolation" during the Cenozoic; during this time, they shared the niches for large warm-blooded predators with the flightless terror birds. Previously, it was thought that these mammals died out in the face of competition from "more competitive" placental carnivorans during the Pliocene Great American Interchange, but more recent research has showed that sparassodonts died out long before eutherian carnivores arrived in South America. Sparassodonts have been referred to as borhyaenoids by some authors, but currently the term Borhyaenoidea refers to a restricted subgroup of sparassodonts comprising borhyaenids and their close relatives.

The International Thylacine Specimen Database (ITSD) is the culmination of a four-year research project to catalogue and digitally photograph all known surviving specimen material of the thylacine held within museum, university, and private collections.

Certainly in my experience this is by far the most thorough compilation focused on an extinct or endangered animal ever produced and, as such, bound to be enormously useful to many generations of scientists to come.

<i>Nimbacinus dicksoni</i> Extinct species of marsupial

Nimbacinus dicksoni is an extinct thylacinid marsupial, a close relative of the recent but extinct thylacinid known as the Tasmanian tiger. It lived approximately 23-16 million years ago in the Miocene period. Nimbacinus dicksoni was about 1.6 ft (0.49 m) long. Being a predator, it likely ate birds, small mammals, and reptiles. Like the recently-extinct thylacine, it may have been an awkward runner and used stamina to catch prey rather than speed. Fossils have been found in Australia at Riversleigh in north-western Queensland and Bullock Creek in the Northern Territory.

<i>Thylacinus potens</i> Extinct species of marsupial

Thylacinus potens was the largest species of the family Thylacinidae, originally known from a single poorly preserved fossil discovered by Michael O. Woodburne in 1967 in a Late Miocene locality near Alice Springs, Northern Territory. It preceded the most recent species of thylacine by 4–6 million years, and was 5% bigger, was more robust and had a shorter, broader skull. Its size is estimated to be similar to that of a grey wolf; the head and body together were around 5 feet long, and its teeth were less adapted for shearing compared to those of the now-extinct thylacine.
