Pangea was roughly shaped like Pac-Man, with land reaching to both north and south poles and a chunk biting into the middle that contained the Tethys Sea, explains Paul Olsen, a paleontologist at Columbia University. Over the millions of years of its existence, this supercontinent saw the flourishing of bio ...read more
