Finding a partial Thylacoleo - Day 4Video | Updated 3 years ago This video documents the process of finding a partial Thylacoleo skeleton, and the difficulties that can sometimes arise when moving around such tight spaces. Transcription On our other trip we discovered another partial Thylacoleo skeleton, with a jaw and part of a skull showing in the sediment, so we’re just going to go in and have a look. (crawling through tight cave spaces) Just moving around like a worm… I sort of came up a different way, and it’s a tad tight. The Thylacoleo was Australia’s top predator. It had very powerful claws with opposable thumbs. It’s roughly the size of a jaguar, and it probably had one of the most powerful bite forces of any known predator. View the discussion thread.
