Megalodon is NOT alive today, it went extinct around 3.5 million years ago.

Bottom line: A new study suggests that particles from a supernova raining onto Earth 2.6 million years ago killed off large ocean animals – including the huge megalodon shark.

Megalodon (Carcharocles megalodon) was a species of shark that lived during the Miocene and Pliocene epochs (23.03 million to 2.58 million years ago).

Did Megalodon live at the same time as humans? 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.

Recently the spinosaurus was found to have a crocodile/tadpole like tail. This would make it a much more efficient swimmer than first thought. Spinosaurus pros: more agile and had claws, would beat megalodon on land lol, great swimmer, hunted large swordfish almost as big as the meg.

Well, scientists guess that even the biggest Megalodon only reached a mere 58 feet (18 meters) (though some argue it was up to 82 feet [25 meters]). By contrast, the largest blue whales clock in at a little more than 100 feet (30 meters) long, and on average are between 75-90 feet (23-27 meters) in length.

A pod of carnivorous whales, orca size (20–30 feet) or larger, could kill a megalodon.

That’s up in the air right now. With the strongest bite force on record for any animal at any time (41,000 psi), the Megalodon boasted quite a vicious bite. That’s 5x the bite strength of the Tyrannosaurus rex. That’s strong enough to kill any animal, including a killer whale.

Sperm Whales have sharp teeth and are dangerous predators so Sperm Whales have a chance of killing Megalodon. Blue Whales have the advantage to. They stand from 80–100 feet as the biggest animal. They are colossal and can use jaws and size as an advantage against the huge 60 feet Megalodon.

Comparison With Modern Day and Extinct Animals Megalodon has also been found to be far larger than the gigantic theropod dinosaurs such as Spinosaurus, T-Rex, as well as the large ocean going marine reptiles such as Basilosaurus, and Tylosaurus.

long and was equipped with sharp deadly teeth that could grow to lengths of over 7 inches long making them one of the most deadly predators against dolphins and whales. long the Megalodon would be twice as large as the killer whale (one of the only cetaceans known to hunt and kill sharks and other marine mammals).
