Megalodon died out, probably on the border of the Pliocene and Pleistocene, about 2.6 million years ago, although there are a number of reports of Pleistocene finds. Sometimes called the figure 1.6 million years ago. For teeth raised from the ocean floor, some researchers, based on the growth rate of the crust of deposits, received an age of tens of thousands and even hundreds of years, but this method of determining age is unreliable: the crust can grow at different rates even in different areas of the same tooth, and may stop growth for unclear reasons.
