On of the great tragedies of the 20th century was the extinction of the Tasmanian tiger, the largest carnivorous marsupial to have lived in the modern word. Bad enough that this rare beast, found only on the Australian mainland New Guinea and Tasmanian is gone but that its demise was mainly caused by the incursions and depredation of European settlers. It looked very much dog-like im body style and size. In length the Tasmanian Tiger averaged between 3.5 and 4.5 feet long with a tale about two foot long.
