Otodus megalodon was a gigantic megatooth shark that lived in the world’s oceans from 23 to 3.6 million years ago. It could grow to the enormous size of at least 15 m long, making it one of the largest apex marine predators since the Mesozoic. In new research, paleontologists tested hypotheses relating to Otodus megalodon’s extinction by providing quantitative estimates of its body temperature. They found that thereby constraining its thermal...
