Tooth analysis confirms megalodon was warm-blooded

A team of international researchers have found that Megalodon, a shark species, was actually warm-blooded or “regionally endothermic.” However, this characteristic has resulted in its extinction. Read more here.

Though megalodon was quite bit warmer than both of these modern apex predators, making it unique, says author

The worlds largest-ever and most terrifying marine predator may have died out because of this.

Findings might help explain why the giant shark went extinct 3.6 million years ago

A new study shows that the gigantic Megalodon, or megatooth shark, was warm-blooded: providing the first empirical evidence of warm-bloodedness in the extinct shark. This latest research on the Megalodon, which lived in the world’s oceans from 23 million to 3.6 million years ago and measured about 50 feet in length, appears in the peer-reviewed journal Proceedings of the National Academy of Sciences. The study, conceived of and led by Michael Griffiths and Martin Becker, both professors of env...

O. megalodon sharks were warm-blooded megapredators. But colder-blooded great white sharks may have had an evolutionary edge when food sources dwindled.

The world's largest-ever marine predator which roamed the seas millions of years ago may have died out because it was warm-blooded.

The megalodon, a huge shark that was the scourge of the ancient oceans and is a star in modern movie theaters, is named for its "large tooth" - and for good reason. Its serrated teeth - up to about 7 inches long (18 cm) - could tear through any prey in the deep blue sea. Researchers estimated that megalodon, which reached at least 50 feet (15 meters) and possibly 65 feet (20 meters) long while hunting marine mammals including whales, boasted an overall average body temperature of abo...
