The Thylacine was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century. It was the last extant member of its genus, Thylacinus, although several related species have been found in the fossil record dating back to the early Miocene. The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but it survived on the island of Tasmania along with several endemic species, including the Tasmanian Devil. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributory factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite being officially classified as extinct, sightings are still reported. An apex predator, it was not related to placental mammals, but because of convergent evolution it displayed the same general form and adaptations. The Thylacine was one of only two marsupials to have a pouch in both sexes (the other is the Water Opossum). The male Thylacine had a pouch that acted as a protective sheath, protecting the male's external reproductive organs while running through thick brush.

For one human being to love another: that is perhaps the most difficult of all our tasks, the ultimate, the last test and proof, the work for which all other work is but preparation.   --Rainer Maria Rilke
