When did Megalodon live?
Megalodon lived from 17 million (period: Tertiary. Epoch: Miocene) until 2 million years ago (period: Quaternary. Epoch: Pleistocene). Humans appeared for the very first time around 100,000 years ago, meaning we never met Megalodon in person; neither did dinosaurs, which became extinct around 65 million years ago, long before Megalodon appeared.
