Much lighter than bone, cartilage allows sharks to stay afloat and swim long distances while using less energy. Periodic messages.
There is no evidence of the megalodon's continued existence in the shallow seas that served as their nursery and hunting grounds nor any bite marks of the right size on the animals that would be their prey. Fossils uncovered by paleontologists give a sense of the shark's massive size and strength. Megalodon teeth are no different, and their teeth can be found scattered on coastal beaches or just offshore. Whereas Great Whites dive straight toward their prey's soft tissues (say, a carelessly exposed underbelly or the legs of a wading swimmer), Megalodon's teeth were especially suited to biting through tough cartilage, and there's some evidence that this giant shark may have first sheared off its victim's fins (rendering it unable to swim away) before lunging in for the final kill.

In the Sant Ocean Hall, a gaping megalodon jaw filled with teeth is a favorite place for museum-goers to snap a group photo or selfie. Megalodon was a giant shark who prowled the ancient seas 15 to 1.6 million years ago. The barrier led to the creation of pairs of related species, such as the Pacific goliath grouper and the Atlantic goliath grouper, but other species didn’t fare so well. Most modern depictions paint megalodon as looking much like a supersized great white shark, and much of that is due to the fact that scientists thought for quite some time that the great white and megalodon shared a common ancestor. Since Megalodon is known by thousands of fossilized teeth but only a few scattered bones, its exact size has been a matter of contentious debate.
They likely could tear chunks of flesh from even the largest whales of the time. These locations provided the shark pups with plenty of fish and a safe environment to grow, away from the larger predators of the open ocean and offshore zones.
Scientists calculate that a bite from a megalodon jaw could generate force of up to 40,000 pounds, which would make it the strongest bite in the entire animal kingdom.
Carcharocles megalodon was once the most fearsome predator to reign the seas. During the early and middle parts of the Miocene Epoch (which lasted from 23 million to 5.3 million years ago), large seaways separated North America from South America and Europe and Asia from Africa and the Middle East, which likely facilitated movement from one ocean basin to another. Print.
Scientists posit that this shallow warm-water nursery provided young megalodons with access to a diverse array of smaller, more-abundant prey and enabled adults to better intercept attacks from other predatory shark species, such as hammerhead sharks. Thanks for signing up for Ocean Conservancy emails. August 15, 2014 Updated: August 17, 2014.
Cordoned off from the nutrient-rich waters of the Pacific, Caribbean species needed to adapt.
Over the past century, paleontologists have come up with estimates, based mainly on tooth size and analogy with modern Great White Sharks, ranging from 40 to 100 feet from head to tail, but the consensus today is that adults were 55 to 60 feet long and weighed as much as 50 to 75 tons--and some superannuated individuals may have been even bigger. Thats because sharks have skeletal structures made out of cartilage and not bone. Tooth-shape similarities between megalodon and modern great white sharks (Carcharodon carcharias) suggest that the two species may have been close relatives, and thus megalodon likely resembled that species in appearance—that is, as a bulky torpedo-shaped fish with a conical snout, large pectoral and dorsal fins, and a strong crescent-shaped tail.
2. You have to go back 65 million years--to none other, once again, than Tyrannosaurus Rex—to find a creature that possessed bigger choppers, though the protruding canines of some saber-toothed cats were also in the same ballpark. The answer, in short, is not a lot. Just some teeth and sections of a Vertebral column. This has been the case from antiquity (Pliny the Elder thought that the teeth fell from the sky during lunar eclipses) to modern times. That all changed when the Pacific tectonic plate butted up against the Caribbean and South American plates during the Pliocene, and the Isthmus of Panama began to take shape.

But later during the Pliocene, there was a drop in ocean temperatures that likely contributed to the megalodon’s demise. Fossils of megalodons have been found nearby every continent except for Antarctica. Fact #1. Bodyweight estimates vary, Here are 10 fascinating Megalodon facts. Roughly up to 3 times the length of a modern-day great white shark, it is the largest shark to have ever lived. Modern research shows that the megalodon is most closely related to mako sharks, not to the Great White. If these animals were in fact alive, scientists say, there’s no way we wouldn’t have at least some idea of it. But we do have fossilized megalodon teeth, as they’re made of a hard calcified tissue called dentin. C. megalodon Extinct by 2.6 million Years Ago The giant prehistoric shark known as Megalodon (C. megalodon) has certainly attracted a lot of scientific attention in recent years. Female megalodons were, on average larger, at about 44 to 56 feet (13-17 m) and males were about 34 to 47 feet (10-14 m). While that isn’t as impressive as some of the wild claims that this shark was over a 100 feet long and weighed over 150 tons, it’s still pretty big. Megalodon pictures, on the other hand, often tell a different story. large mammals in the ocean were undergoing significant changes. Unlike some other marine predators from prehistoric times—which were restricted to coastlines or inland rivers and lakes—the megalodon had a truly global distribution, terrorizing its prey in warm-water oceans all over the world.
