Their back feet also included a naked pad along the entire bottom surface from toe to heel, and they walked on the whole surface of their back feet, which is also something dogs don’t do. Thylacines had more cat-like front legs and feet that could rotate, spread and even grasp, unlike dogs. People are reporting sightings of the Tasmanian tiger, thought to be extinct The males had scrotal pouches into which they could retract their scrotum, but it’s still unknown why.Ī very distantly related yapok, or water opossum, used it to insulate and protect the scrotum while swimming, but thylacines weren’t likely to be swimming around, he said.Ī Tasmanian tiger, which was declared extinct in 1936, displayed at the Australian Museum in 2002. Female thylacines carried their young in their pouches. Instead, thylacines likely hunted anything under 18 to 22 pounds, like small marsupials including bandicoots, pademelons, bettongs and small wallabies.Īlthough the last of the thylacines died out in captivity in the 1930s and there is actual video footage of them, thylacines present a mystery to researchers because there are no direct observations to suggest information about their behavior and biology.Īs marsupials, both males and females had pouches but they served different purposes, Rovinsky said. “And, it also moves the thylacine further away from the idea of it being a “marsupial wolf,” because wolves are big, highly-specialised predators of big, dangerous prey.” “It was probably a mid-sized predator, doing what mid-sized predators do best: hunting and eating small animals,” Rovinsky said. “Finding out that they were smaller than previously thought really does change our views on the predatory behaviour of the thylacine,” said Douglass Rovinsky, lead study author and postdoctoral student at Monash University in Australia, via email.įarmers were wrong in assuming thylacines could kill their livestock. Instead, thylacines likely hunted small prey and probably didn’t hunt in packs to take down prey much larger than themselves. Predators more likely to take on large prey, like wolves, are typically 46 pounds or larger. But an analysis of thylacine skeletons showed their smaller bodies weren’t adapted to handle the stress of hunting larger prey. This misunderstanding about their size led farmers to believe thylacines could be dangerous to livestock. The scientists discovered that males averaged about 42 pounds and females reached 30 pounds, which shifts the understanding of their role in the Australian ecosystem. Researchers used advances in 3D scanning and analysis to study 93 thylacine museum specimens from six countries. 'Precious' footage from 1935 of last-known Tasmanian tiger released Courtesy National Film and Sound Archive of Australia Taken from the travelogue Tasmania The Wonderland, the images (shot in 1935) are thought to be the last ever filmed of a thylacine named 'Benjamin,' months before his death in 1936. The study published Tuesday in the journal Proceedings of the Royal Society B.Ī 21-second newsreel clip featuring the last known images of the extinct thylacine (or Tasmanian Tiger) filmed in 1935, has been digitised in 4K and released by the National Film and Sound Archive of Australia (NFSA). These creatures, once estimated to be about 65 pounds, were really only about 37.5 pounds on average and rather cat-like, new research has suggested. This was shortly after thylacines had been granted protection status, but it was too late to save what researchers call an “icon of Australian biodiversity.” The last thylacine living in captivity, named Benjanmin, died from exposure in 1936 at the Beaumaris Zoo in Hobart, Tasmania. The shy, semi-nocturnal thylacines were hunted down to the point of extinction. When settlers began establishing sheep and cattle farms in Tasmania in the 1800s, thylacines were blamed for livestock losses that were actually due to feral dogs and human mismanagement. Thylacines, with their defining striped coats and an odd combination of features, went extinct about 2,000 years ago everywhere except the island of Tasmania. This development has suggested that the now-extinct marsupials were about the size of large coyotes rather than wolves. Tasmanian tigers, otherwise known as thylacines, were about half the size scientists once estimated them to be.
