Its “shark week” in the image below is a picture of a well preserved Megalodon upper/lower jaw bone. The smaller jaw bone is that from a great white shark. Megalodon could reach the size of 30-60 feet and its teeth were 1-3 feet long!!! Good thing these guys are extinct, although I wonder how long it will take to put braces on this big guy!
