There is some controversy over the preferred prey size of the thylacine. A 2011 study by the University of New South Wales using advanced computer modelling indicated that the thylacine had surprisingly feeble jaws. Animals usually take prey close to their own body size, but an adult thylacine of around was found to be incapable of handling prey much larger than . Thus, some researchers believe thylacines only ate small animals such as bandicoots and possums, putting them into direct competition with the Tasmanian devil and the tiger quoll. Another study in 2020 produced similar results, after estimating the average thylacine weight as about rather than , suggesting that the animal did indeed hunt much smaller prey.
