Researchers have finally revealed the fame of prehistoric mega-sharks in Hollywood movies.

So far, the length of Otodas Megaldon appearing in the 2018 film The Meg was estimated from the fossils of his teeth.

But a team from the universities of Swansea and Bristol have combined mathematics with nature to reveal how big it was.

The study was published in the journal Scientific Reports.

Researchers used mathematical methods and comparisons with living relatives to find the overall size of the Magellan, which lived about 23 million to 30 million years ago.

Results 1 suggest meter (52 feet) The megalodon – about three times longer than a great white shark – can have a head about 4,655 meters (15 feet) long, have a dorsal fin like a full adult human, and have a tail about 3.75 meters ( 13 feet) high.

Jank Cooper, who is studying for a PhD in paleobiology at Swansea University, described the study as his “dream project.”

“Megaldons are the animals that inspired me to pursue paleontology, but it’s hard for us to study the whole animal as it really is a lot of isolated teeth,” he said.

“It is significant that we are now able to produce estimates of the proportions and dimensions of body parts when we cannot leave fossils.

“But the dimensions of the picture were actually quite accurate.”

Previously, the shark was only compared to the great white, but the latest analysis was extended to include five modern sharks, including the macaws, salmon sharks and porpigel sharks.

Mr Cooper added: “We can take the growth curve of the five modern forms and create the overall shape as they grow larger in body length from 1 to 16 meters.”
