You really shouldn't be trying to use evidence like that when you don't understand the meaning of the units of measure involved. Pounds of pressure =/= pound-force. Megalodon had an estimated bite force of 40,000 pound-force, or 180,000 newtons. That does not mean it could exert 40,000 pounds of pressure with its bite.
I should also mention that I find that number extremely
questionable for more than one reason. I believe the estimate of its bite was based off of estimates of the maximum bite force a great white's skull and jaws can handle. This alone is bad for a couple reasons. For one thing, basing an estimate on another estimate is a bad idea. The second is that max bite force estimate for the great white doesn't sych up with actual direct measurements of their bite pressure. A study conducted by Dr. Brady Barr for National Geographic directly measured a great white's bite at around 600 psi. By comparison, the bite of a 10-foot alligator was directly measured at just shy of 3000 psi.
On top of all that, there's the fact that a Megalodon simply wouldn't need anywhere near that much bite force. It had sharp, serrated teeth. And it fed on whales, which are very soft and squishy animals in the grand scheme of things. It would have zero use for such a bone-shatteringly high bite force. And this is supported by the fact that we find fossilized whale bones with tooth marks from Megalodon teeth. Tooth MARKS. As in, scratches and gouges. We have not, however, found whale bones that have been broken
by Megalodon teeth.
