How the Great Dying sparked an evolutionary arms race in the prehistoric oceans
In short: Following the mass extinction event known as the Great Dying, marine reptiles called ichthyosaurs emerged. This video examines how their rise fundamentally reshaped ocean life and triggered a new era of competition between predators and their prey.
The Great Dying resulted in the loss of at least 90 percent of all marine life. This catastrophic event cleared the way for ichthyosaurs to evolve, fundamentally altering the marine ecosystem.
Their emergence initiated an intense evolutionary arms race, driving rapid adaptations in both predators and prey as they navigated a transformed underwater world.
