She presented her findings here at the 73rd annual Society of Vertebrate Paleontology meeting. Bigger is better? Megalodon could grow up to 60 feet 18 meters long and had a bite more powerful than that of a Tyrannosaurus rex. The sea monsters terrorized the oceans from about 16 million to 2 million years ago. Though that may seem like a long reign, other shark species have survived for 50 million years or more without significant changes in body plan, Pimiento said. Megalodon's short history made Pimiento ask whether the shark's body size affected its evolutionary success. Bigger animals can eat a wider range of foods and be fiercer predators than their pip-squeak pals.

But because they eat more types of animals they also have more competition for those animals, and the ecosystem can support a lower population density of them since they need more resources — including space — to survive.

Broader Implications To our knowledge, body-size trends of large predatory sharks have never been studied before over geologic time. Our results have three broader implications that provide a deep-time perspective to the understanding of the body-size trends of marine apex predators: 1. Conclusions We found that Carcharocles megalodon body size had a left-skewed distribution and was significantly different between hemispheres and ocean basins through geologic time.
