Prehistoric Giant Shark Megalodon Had Fins As Large As A Human

Cynthia McKanzie – MessageToEagle.com – The size of the legendary giant shark Megalodon has been revealed for the first time.

Today, the most fearsome living shark is the Great White, at over six meters (20 feet) long, which bites with a force of two tonnes, but it’s a small animal compared with the prehistoric Megalodon that had fins that as large as an adult human.

The big tooth shark Megalodon, star of Hollywood movies, lived from 23 to around three million years ago, was over twice the length of a Great White, and had a bite force of more than ten tonnes.

The big tooth shark Megalodon, star of Hollywood movies, lived from 23 to around three million years ago, was over twice the length of a Great White, and had a bite force of more than ten tonnes.

The fossils of the Megalodon are mostly huge triangular cutting teeth bigger than a human hand.

Using a number of mathematical methods to pin down the size and proportions, scientists from the University of Bristol and Swansea University have now revealed the terrifying scale of the legendary Great White ancestor the Megalodon from new fossil finds.

“I have always been mad about sharks. As an undergraduate, I have worked and dived with Great whites in South Africa – protected by a steel cage of course. It’s that sense of danger, but also that sharks are such beautiful and well-adapted animals, that makes them so attractive to study.

Megalodon was actually the very animal that inspired me to pursue paleontology in the first place at just six years old, so I was over the moon to get a chance to study it.

This was my dream project. But to study the whole animal is difficult considering that all we really have are lots of isolated teeth,” Jack Cooper at the University of Bristol’s School of Earth Sciences said.

Previously the fossil shark, known formally as Otodus megalodon, was only compared with the Great White. Jack and his colleagues, for the first time, expanded this analysis to include five modern sharks.

“Megalodon is not a direct ancestor of the Great White but is equally related to other macropredatory sharks such as the Makos, Salmon shark and Porbeagle shark, as well as the Great White. We pooled detailed measurements of all five to make predictions about Megalodon,” Dr. Catalina Pimiento from Swansea University said.

“Before we could do anything, we had to test whether these five modern sharks changed proportions as they grew up. If, for example, they had been like humans, where babies have big heads and short legs, we would have had some difficulties in projecting the adult proportions for such a huge extinct shark.

But we were surprised, and relieved, to discover that in fact that the babies of all these modern predatory sharks start out as little adults, and they don’t change in proportion as they get larger,” Professor Mike Benton, a paleontologist at Bristol University added in a press statement.

Jack Cooper said: “This means we could simply take the growth curves of the five modern forms and project the overall shape as they get larger and larger – right up to a body length of 16 meters.”

The results suggest that a 16-meter-long Otodus megalodon likely had a head round 4.65 meters long, a dorsal fin approximately 1.62 meters tall, and a tail around 3.85 meters high.

This means an adult human could stand on the back of this shark and would be about the same height as the dorsal fin.

The reconstruction of the size of Megalodon body parts represents a fundamental step towards a better understanding of the physiology of this giant, and the intrinsic factors that may have made it prone to extinction.
