morons...
Tell me, what large animals, or fish species, are still around that thrived 3 million years ago??
Bueller? Bueller???
Gators and Crocs
Bueller replies… two examples..
1. The oldest known coelacanth fossils are over 410 million years old. Coelacanths were thought to have become extinct in the Late Cretaceous, around 66 million years ago, but were discovered living off the coast of South Africa in 1938.[6][7] and are still caught by fishermen.
2. Horseshoe crabs are often referred to as living fossils, as they have changed little in the last 445 million years.[8] Forms almost identical to this species were present during the Triassic period 230 million years ago.
