A prehistoric crocodile, 5m in length, lived in SE Queensland wetland evirons for most of the last 55 million years. Its skull measured around 65cm and it is estimated it would have been roughly the size of a modern Ino-Pacific crocodile, as far as length is concerned. However, teh prehistoric crocodile had bigger biting and munching capabilities. Crocodiles have been a feature of Australasia for a long time, and are still regarded as a dangeerous hazard. TGhey appear to have survived the K/t boundaray event [or K/Pg as it is now known].

Over at https://phys.org/news/2020-12-crazy-beast-dinosaurs.html … which concerns a mammal that lived amongst the dinosaurs. By the artists impression at the link it looks something like a badger and even has claws. An almost intact skeleton was unearthed in Madagascar recently and has been the subject of study which resulted in a monograph. It was the size of an American oppossum we are told, just 3.1kg in weight. So, nothing like a badger. It is described as a giant shrew.
