Megalodon and Great White Sharks

I saw a picture this week of what was reported to be the upper and lower jaws and teeth of megalodon compared to that of a much smaller contemporary great white shark and was reminded of some reflecting on the mystery of megalodon’s existence and extinction from a few years ago:

“Just pondering….. if megaladon was the largest shark species to ever live and went extinct over 3 million years ago, since no complete intact skeleton has ever been found, how do we know it was not just a great white shark that lived at a time when the oceans were rich and not highly commercially fished and earth’s population not so large and wide ranging? Maybe a lot of species lived longer and grew larger then, but are not separate species at all? After all there was a time that the Bible tells us people lived several hundred years, too, before the widespread civilization of the earth and burgeoning population. Maybe God limited the damage and extensive influence that could be accomplished by such generational longevity of any species……”. CBB 5/17/2021
