I am thinking a 61 ton fish living in cold water needs to eat at least a thousand pounds of protein and fat every day.

Roughly, that would be 120 cans of tuna fish every hour - with no breaks.

They are not extinct. They still exist in the remote recesses of the worlds more isolated and deeper entrenchments, waiting to ppouce , devour and create another mystery missing boat.

BUahahahahahahahahah!

Imagine the orthodontics bill on a megalodon.

Big deal, so could Jerrold Nadler.

Just why this formidable predator went extinct remains a mystery. It could have been linked to global cooling, or competition from other predators such as orcas (killer whales). This is just one of many unanswered questions.

A lot of these things come down to physiology -- which is hard to reconstruct. Assume a 61 ton, cold blooded toothed fish. Probably not real fast. Something like a modern Whale Shark... not fast enough to stay with a pod of whales in open ocean. So it hangs in the shallow seas where it probably can't use the 3rd dimension to ambush like a modern GW Shark. So what is it feeding on? Has to be something big and relatively easy to catch.

All that based on a nearly complete set of vertebrae....
