(CNN) The true size of a gigantic prehistoric megalodon shark that ruled the oceans millions of years ago has been revealed for the first time -- and it had teeth as big as hands, and a fin as tall as a human adult. Researchers at the University of Bristol, in southwestern England, and at the Swansea University, in south Wales, used mathematical calculations to work out the size of the megalodon shark from rare fossil remains of its teeth. Researchers told CNN that the giant shark species would have grown up to 18 meters (59 feet) in length and weighed about 48 tons, which is larger than any other shark known to have existed and more than twice the size of a great white shark. Measuring an estimated 1.6 meters (5.3 feet), the megalodon's fin was as tall as an adult human. "There have been some fossils found with large serrated bite marks on them that would incriminate megalodon as the attacker," Cooper told CNN.
