We see the platypus as a quiet curious animal always on the go, but millions of years ago it was twice as big and had vicious teeth. It hunted turtles crayfish and frogs. Paleontologists have called it Platypus Godzilla because it would have been quite vicious.
The modern platypus, Obdurodon tharalkooschild, is only half a meter long. Its quiet, secretive life could indicate that it is heading for extinction. Identifying platypus fossils is easy if teeth are found, because they are so different from other species.
Platypus teeth are blunt. The animals must have "bruised" their prey to death. Fossils of the ancient platypus were not ancestors of modern platypus. They were a side branch "experimenting' with being a larger size.
Just why platypus millions of years old had functioning teeth while modern ones have virtually lost theirs is not known. Despite being good a hunter Godzilla did itself go extinct. Modern tharalkoo live in a narrow niche. If there is drastic change in the environment they will perish.
