Megalodon is an extinct species of shark that lived approximately 28 to 1.5 million years ago, during the Cenozoic Era. The taxonomic assignment of C. megalodon has been debated for nearly a century, and is still under dispute.
The Miocene epoch (23.03 to 5.332 million years ago) boasted a real life sea monster, Carcharocles megalodon. Whereas the giant shark mainly inhabited the open ocean, this image depicts a hypothetical encounter with a swimming Platybelodon, a prehistoric mammal related to the elephant. The bones of these elephantids sometimes show evidence of attack by sharks.
