In reality, this tiger probably looked more dog-like than a tiger. Though there were later reports of Tasmanian wolves being seen in the wild, this species is still considered to be extinct. An engineering technique called “finite element analysis” was used to digitally construct the skull of the thylacine and two living relatives – the Tasmanian devil and spotted-tailed quoll. Kangaroos are killed by standing on them and biting through the short rib into the body cavity and ripping the rib cage open”. Its extinction in the wild (1932) was caused by the introduction of dogs, and by people actively hunting the animal.

The factors involved in the historical decline of contemporary mammals need to be identified to guard against future biodiversity loss, argues Marie Attard. Telephone.

That might sound like a very specific date to know when anything went extinct, and it is. Answer. The mechanical performance of the thylacine skull may provide clues into their mode of hunting and disclose limitations in the size of prey they could catch. Among these are competition with dogs, habitat loss and changing fire regimes leading to population fragmentation, and an epidemic disease that spread through the population in the 1920s.
