Does the Tasmanian Tiger still roam the island state, parts of the Australian mainland, and the northern land mass of Irian Jaya-Papua New Guinea? Despite being hunted to extinction in the early part of the 20th century, the Tasmanian Tiger continues to stalk the imaginations of people the world over. What's more, hundreds of reports of the striped dog-like marsupial with the fearsome gaping jaw are made each year in Australia. In The Tasmanian Tiger: Extinct or Extant?, biologists, geneticists, naturalists, and academics explore the evidence for and against the continuing existence of Thylacinus cynocephalus.
