The extinct shark Otodus megalodon was a transoceanic super-predator: Inferences from 3D modelling
Although shark teeth are abundant in the fossil record, their bodies are rarely preserved. Thus, our understanding of the anatomy of the extinct Otodus megalodon remains rudimentary. We used an exceptionally preserved fossil to create the first 3D model of the body of this giant shark and used it to...
