Rather you than me I assume you have been taken in by the claims by some researchers that they were actually frugivorous, but this has now been refuted.
Frugivorous? With those carnassials? No way!!! Thylacoleo was a large carnivore, but not as large as a lion, more a small leopard - only a metre and a half long in total and less than a metre in height. They most likely would not attack an adult human under normal circumstances. I believe I could probably stare one down, or fend it off with a big stick. Unless, of course, it was a pack animal. Hix
As I noted, there have been revisionists intent on establishing it as such, amazing though this may seem. However, it was very powerful for its size, with a 100kg individual possessing a pound-for-pound bite force equalling that of a big cat more than twice its size and weight. And it was a lot heavier set than a placental cat. Basically, rather than a small marsupial leopard it would be more accurate to think of it as a bloody big wombat with a very bad attitude problem
Come on! How can you say that? For all you know they might have liked rubbing up against people's legs! Hix
