Great Whites May Have Taken Out Megalodon 3.6 Million Years Ago | SciShow News

The video discusses the extinction of the Megalodon, a giant prehistoric shark, and the scientific debate surrounding its timeline. A new study suggests Megalodon went extinct 3.6 million years ago, a million years earlier than previously thought, possibly due to competition with great white sharks. The video also explores the recent decline of great white sharks off South Africa's coast, leading to the rise of 7 gill sharks as top predators. Researchers aim to understand these changes and their impact on marine ecosystems.

What were the previous theories regarding the cause of Megalodon's extinction, and how do they change with the new findings?

What implications does the presence of seven gill sharks have for the ecosystem dynamics in the absence of great white sharks?
