New very important fossil discovery

In Kimberley, West Australia, a new 380MYO fossil fish called Gogonasus has been discovered.

The fish had large holes for breathing through the top of it's head and muscular front fins with a well formed humerus, ulna and radius (same as humans)

This discovery means humans can trace their evolutionary roots back further than before, to more than 380 million years ago, and raises the possibility that tetrapods originally evolved in the southern hemisphere, in Gondwana, as opposed to the northern hemisphere as was previously thought.
