It seems that the huge shark had a massive head, judging by the fact that 1/3 of the whale was dissected with one bite, and the crowds also found a huge tooth in the dissected body. Whether or whether not it was a Megalodon, it definitely should get the biologists excited!
Estimates of Megalodon range from 39-101 feet long and a jaw width of 7 feet or more.
Fossils of Megalodon teeth and the occasional bone have been distributed all over the world, except for cold water regions. Its fossils are most common in Europe and North America
Megalodon fossils date back to the late Ologocene at around 28 million years ago to the Pleistocene barely 1 or 2 million years ago. If they are still alive today, sightings of Leviathan are more explainable.
Nothing was off-limits for Megalodon! Whales, sealions, even other Megalodons!
Megalodon was not alone in the big predator list of its time. Livyatan was a massive 17m long predatory whale of the same age that was easily a rival. In shallow waters, it could have encountered Purrusaurus, a giant crocodilian almost 15 m long that probably frequented the shallow seas. There were also packs of Brygmophyseter (a species of sperm whale) and Squalodon (a killer whale sized cetecean with a narrow snout filled with razor sharp teeth)
