Megalodon's body size and form uncover why certain aquatic vertebrates can achieve gigantism

A new study provides many new insights into the biology of the prehistoric gigantic shark megalodon (megatooth shark), which lived nearly worldwide 15–3.6 million years ago. Paleobiology professor Kenshu Shimada of DePaul University led the study along with 28 other shark, fossil, and vertebrate anatomy experts from around the globe. Findings from the study are published in the journal Palaeontologia Electronica.
