The great white shark is a formidable oceanic hunter. Its powerful jaws are capable of exerting over 4,000 pounds per square inch (PSI) of bite force — enough to shatter a human femur. But compared to the megalodon, a giant prehistoric shark that roamed the oceans from 15 million to 3.6 million years ago, the great white seems like a mere minnow. The megalodon had a sleek body estimated to exceed 60 feet in length, according to a 2024 paper published in Palaeontologia Electronica, dwarfing it ...read more
