It's known as the megalodon, believed to be the largest shark species to ever exist. Evidence in the teeth and bite marks found on fossilized bones suggest these ancient sharks were swimming the ocean between 23 million and 3.5 million years ago.
Megalodons are extinct. They died out about 3.5 million years ago. And scientists know this because, once again, they looked at the teeth. All sharks – including megalodons – produce and ultimately lose tens of thousands of teeth throughout their lives.
Since sharks don't have bones, most of what we know about megalodon comes from its large fossil teeth. The largest megalodon tooth ever found was 6.9 inches long. That's almost three times longer than the average tooth of a modern great white shark.
Megalodon was first described in 1835 by Swiss-born American naturalist, geologist, and teacher Louis Agassiz, who named the species Carcharodon megalodon. Megalodon would be known by this scientific name until the late 1990s, when a growing group of scientists placed it in the genus Carcharocles.
Tooth Size Can be Used to Estimate Body Size
Among the great ways scientists used to determine the true size of Megalodon was a study of the size of its teeth. Some Megalodon teeth have a slant height of more than seven inches, which is a very large tooth.
Is the megalodon still alive? 'No. It's definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,' notes Emma. 'If an animal as big as megalodon still lived in the oceans we would know about it.'
First, you wouldn't be much larger than the megalodon's dorsal fin, which scientists have estimated to be around 5 feet and 3 inches tall. You would be less than half the height of their tall, which could be nearly 13 feet tall – that's about half the length of a London bus!
Megalodon, the biggest shark that ever lived, may have been killed off thanks to the success of the great white, new research suggests. A study of elemental traces in their teeth implies the huge sea monster faced competition for resources from its smaller and more nimble rival, say scientists.
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and ...
To give you a general price range for commercial grade (has some defects) Megalodon teeth. 2-3” teeth will typically be in the $20 to $60 range, 3-4” teeth will fall into the $50-100 range, 4-5” teeth the $100-200 range, 5-5 ½” teeth $200-400, etc.
There is no evidence that scientists are currently trying to bring back the megalodon. In fact, its doubtful that they ever will. This is because the megalodon went extinct millions of years ago. And there is no way to bring it back since theres no viable DNA to clone them.
As of yet, no one has seen a Megalodon, also known as a Megatooth shark, which reportedly went extinct around 2.58 million years ago, according to the Encyclopedia Britannica.
Megalodons succumbed to global cooling due to the shrinking of their habitat, the vanishing of their favorite prey, and competition from other predators 3.5 million years ago.
His largest monster, a 17-foot Great White Shark weighing 3,427 pounds, in some record books still remains the largest fish ever caught by rod and reel. Mundus moved to Montauk from New Jersey in 1951 to pursue a career catching groundfish (Striped Bass, Black Seabass, Bluefish etc).
Some megalodons are estimated to have been much larger―as long as 50 feet. Using the data from this study, together with previous research, the researchers concluded that the potential lifespan of megalodons was 88-100 years.
Pinnipeds (seals and sea lions) aren't the only marine mammals that have snacked on a shark. The sperm whale is a marine mammal that is considered an apex predator in certain habitats and it has been recorded as having eaten shark eggs.
The Spinosaurus, the biggest land predator of all time, had a mouth similar to a crocodile's, and it had straight teeth like knives. The title of largest land predator that ever walked on Earth goes to the Spinosaurus. This meat-eating dinosaur lived about 90-100 million years ago.
Megalodon is NOT alive today, it went extinct around 3.5 million years ago.
Great white sharks evolved about 4 million years ago, overlapping with megalodon for approximately 400,000 years, Live Science previously reported. At first, megalodon and great whites occupied separate niches and didn't compete with one another.
News Across the U.S.
The megalodon was one of the largest predators that ever lived up until its extinction 3.6 million years ago, according to the Natural History Museum in the United Kingdom.
The Otodus megalodon, commonly called the megalodon, is famous for its massive size. Weighing up to 50 tons and measuring up to about 60 feet in length, the meg was the largest shark ever to exist.
Growing larger may have helped megalodon reduce heat loss, could have improved their ability to cover large distances and allowed them to hunt bigger prey. This could help scientists assess how sharks living today will change as water temperatures are altered by a warming world.
