A new study shows the Megalodon, a gigantic shark that went extinct 3.6 million years ago, was more slender than earlier studies suggested. This finding changes scientists’ understanding of Megalodon behavior, ancient ocean life, and why the sharks went extinct. The Megalodon or megatooth shark is typically portrayed as a super-sized monster in popular culture, with recent examples in the sci-fi films “The Meg” (2018) and “Meg 2: The Trench” (2023). Previous studies assume that the shark likely reached lengths of at least 50 feet and possibly as much as 65 feet. However, the Megalodon is largely known only from its teeth and vertebrae in the ...

CHICAGO — A new scientific study shows that the prehistoric gigantic shark, Megalodon or megatooth shark, which lived roughly 15-3.6 million years ago nearly worldwide, was a more slender shark than previous studies have suggested. Formally called Otodus megalodon, it is typically portrayed as a super-sized, monstrous shark in novels and sci-fi films, including “The Meg.” Previous studies suggest the shark likely reached lengths of at least 50 to 65 feet (15 to 20 meters). However, ...
