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.
No, at least not Homo sapiens. The last Megalodon lived around 1.5 million years ago at the latest. While there would have been early human ancestors around at the time, modern humans did not evolve until much later.
Why did megalodon go extinct? We know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. Precisely when the last megalodon died is not known, but new evidence suggests that it was at least 3.6 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.
For Megalodon to have existed 2.6 million years since the last known fossil tooth, there would need to be a sustainable population. Based on its size (you can see how this is done on my Kaiju post) we would expect global numbers, if we assume the largest Megalodon females get is 65.5 tons, of near ~700,000-1.5 million.
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.
The deep ocean is too cold for them to survive. Megalodons were extremely large animals that ate other extremely large animals. Nothing big enough or numerous enough to sustain them lives in the Mariana Trench.
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).
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.
The world's biggest shark Megalodon might have been killed off by the Great White, scientists have revealed. Megalodon faced competition for food from its smaller and nimbler rival, the researchers found. The prehistoric shark lived between 3.6 million and 23 million years ago and were known for their enormous teeth.
Researchers studying sharks in the northwest Atlantic Ocean were shocked after they detected what appeared to be a massive 50-foot “megalodon” on sea scanners below their boat.
The oldest megalodon fossils are fossilized teeth from around 20 million years ago during the Miocene Epoch. A child in England found a megalodon tooth on a beach and it is the oldest one ever found. Megalodon teeth are not uncommon and many are for sale online for as little as 20 dollars.
Today, a life-size model of the now extinct predator hangs from the ceiling above the National Museum of Natural History's new Ocean Terrace Café. Visitors entering the café from the Ocean Hall come face-to-face with one of the largest and most powerful animals to have ever lived on Earth. C.
In some exceptional cases, fossil marine mammal bones have been found with the bite marks of a megalodon. Some sperm whale bones have evidence of megalodon attacks on their foreheads, a part of the whale that would have been rich in fats. Dolphin tailbones have also been found with deep megalodon tooth marks.
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 ...
The largest great white recognized by the International Game Fish Association (IGFA) is one caught by Alf Dean in southern Australian waters in 1959, weighing 1,208 kg (2,663 lb).
The great white shark has killed the most humans resulting in 52 known fatalities, though roughly 300 unprovoked attacks are recorded from the great white.
Tiger Shark
Tiger Sharks can be found along the waters of the eastern, western, and northern coast of Australia. Tiger Sharks are very large sharks that grow between 10 and 13 ft (3.25-4.25 m) and weigh around 849-1,400 lb (385-635 kg).
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep.
The Megalodon weighs in at upwards of 50-70 tons, measuring a span of up to 60-70 feet in length. By contrast, the Blue Whale tips the scale at around 100-110 tons and tops lengths of up to 100 feet. Who Wins on Size? It's pretty obvious that the Blue Whale is the bigger apex predator in this fight.
The megalodon lived in most regions of the ocean (except near the poles). While juveniles kept to the shores, adults preferred coastal areas but could move into the open ocean. The most northern fossils are found off the coast of Denmark and the most southern in New Zealand.
1. Great White Shark. Great white sharks are the most aggressive sharks in the world has recorded 333 attacks on humans, with 52 of them being fatal. The inclusion of this particular species probably comes as no surprise since movies, particularly Jaws, and television shows are quick to show their aggression.
Because of these characteristics, many experts consider bull sharks to be the most dangerous sharks in the world. Historically, they are joined by their more famous cousins, great whites and tiger sharks, as the three species most likely to attack humans.
With its 300 sharp teeth, the great white has the most powerful bite in the animal world - 18,000 Newtons (1,835 kilograms force).
