Since then, scientists have found hundreds of fossilized Megalodon teeth and spinal segments known as centra. Because a sharkâs skeleton is made up of cartilage, which dissolves quickly in ocean water, these are the only Megalodon remains that have survived over millions of years. Scientists are able to learn a lot about Megalodon from these fragments. For example, experts can determine a Megalodonâs age at death by examining the centra. Each centra contains growth rings, sort of like a tree. By counting the rings, their color, and how far apart they are, scientists are even able to determine a Megalodonâs growth rate.
