(''Thylacinus cynocephalus''), commonly also known as the Tasmanian tiger or Tasmanian wolf, which is believed to have become extinct in 1936. 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
