Tasmanian Wolf or Thylacine, Thylacinus cynocephalus The Tasmanian Wolf is not a wolf, but a carnivorous marsupial and a relative of wombats and kangaroos. It even has a pouch. Tasmanian officials promoting ranching paid bounties to hunters. Believed to be extinct for well over half a century, unconfirmed reported sightings persist.
Laysan Rail (1944): The Laysan Rail was a small flightless bird of the Northwest Hawaiian Island of Laysan. It was only 5.9 inches from beaktip to "tail" tip. The rail was initially threatened when domestic rabbits were introduced to Laysan. With no predators to control their numbers the rabbits soon ate the entire vegetation cover on the island. The species is believed to have become extinct on Laysan during 1923. The last rail was seen on Eastern Island in Midway in June 1944.
