Thylacine
The thylacine (Thylacinus cynocephalus), also known as the Tasmanian tiger or Tasmanian wolf, was the largest carnivorous marsupial of modern times. It was native to Australia, Tasmania, and New Guinea, characterized by a dog-like head, stripes on its lower back, and a pouch. Though believed extinct since 1936, it remains a famous example of convergent evolution.
