Thought you may like to 'feast' your eyes upon a few more ancient residents of the regions in and around Australia.
First, moving clockwise from top to bottom, is the Dromornis, ancient Ancestor of the Emu, stood about 3 metres tall,
Second, the Genyornis, Ancestor of the Modern Cassowary, stood between 2-3 metres tall,
Third the Modern Cassowary, a bit smaller but stil NOT to be messed with, very bad tempered in nature btw,
Fourth the fossilised TOOTH of the Megalodn Shark, known to have roamed the waters around Australia, Africa and possibly Sth. America, length ranged between 60 and 80 feet. Kind of make a Great White look like a Guppy...LOL.
