The largest shark ever ‘Megalodon’, which went extinct about 20 million years ago, is the largest fish on record. Scientifically transcribed as Carcharocles megalodon, which means “giant tooth” have given major clues to the scientists about its existence and extinction both.
Essentially, it is difficult to find out the precise facts about Megalodon’s extinction because of the incomplete fossils record. Despite that, a group of researchers from the University of Zurich, in 2014 founded a technique called optimal linear estimation for calculating the age. According to their study, 6 out of 10,000 simulations that means about 1 percent of chances exist that these gigantic sharks are alive. Subsequently, there is no evidence of Megalodon’s existence and hence the scientists believe that they are extinct.
These giant teethed sharks, as per various researches, use to hunt in warm and shallow seas. The shreds of evidence, their teeth, have been found in every continent except Antarctica. According to discovery, these might have gone extinct when the seas would have dried up and hence these sharks would have starved or frozen to extinction.
Talking about their size, there have been numerous arguments in the scientific community about its actual size. Estimations of the shark being 18 meters to 25 meters long are proved by researchers. However, some of them believe that megalodon was just 6 to 10 meters long, approximately.
