Tasmanian tiger is a carnivorous marsupial, which as recently as 1986 officially became extinct in Tasmania. Its academic name is Thylacine. The last documented sighting occurred in 1936.  One of this predator's most frightening characteristics was an ability to open its jaw a full 120 degrees—useful in latching onto and killing its prey.
While some hold out hope that Thylacines still exist in the wild, others believe the animal can be resurrected using modern cloning techniques and DNA samples from a preserved museum female pup's body.
