A megalodon’s jaw and teeth: 3.6 to 23 million years old
Only fragmentary remains of this giant shark have been found, so its appearance and size are not known for certain. Scientists suggest that the maximum length of the megalodon ranged from 47 to 52 feet (the modern great white sharks grow to be 11 feet to 16 feet). In the second photo, a megalodon tooth is lying next to the teeth of a great white shark.
