Here is the largest jaw ever assembled of the stupendous C. megalodon shark – a fish twice as long as the largest great white shark. “Meg” teeth were whale-choppers. Each tooth carried a fine, saw-toothed edge and thick central zone. Whale bones from deposits full of Meg teeth show deep cuts and gouges that match C. megalodon’s dental anatomy. Elephant tribes were on the menu, too. All members of the elephant clan are expert swimmers, and mastodons and mammoths spread across the Pacific. Mastodons dog-paddling in the surf were occasional victims of Meg attacks, as proven by bite-marks on mastodon ribs and vertebrae.
