The sharks that roam today’s oceans can be fearsome, but they don’t really compare to some of the species that dominated the seas millions of years ago. The Megalodon — a massive shark that is thought to have died out around 2.6 million years ago — has left plenty of fossils behind for researchers to find, but determining what exactly killed the species off has proven a big challenge.
As LiveScience reports, new research was presented recently at the annual American Geophysical Union conference that suggests the shark could regulate its body temperatures similar to some species of modern sharks. However, the ancient shark’s much higher body temperature may have been its downfall.
