The First Great Dying | The Late Ordovician Mass Extinction

The Late Ordovician Mass Extinction was the first of the “Big Five” extinction events in Earth’s history and one of the most devastating. Around 445 million years ago, nearly 85% of all marine species disappeared in a global climate catastrophe that reshaped life on our planet.

In this documentary, we explore what caused the Ordovician extinction, how massive ice sheets formed across Gondwana, why global sea levels dropped dramatically, and how rapid climate change triggered the collapse of ancient marine ecosystems dominated by trilobites, brachiopods, and early reef communities.

Discover the science behind one of the most important events in paleontology and Earth history. Through fossil evidence, geological data, and climate research, we uncover how this ancient extinction event paved the way for evolutionary change during the Paleozoic Era.

If you’re interested in mass extinctions, prehistoric oceans, ancient climate change, paleontology, and the deep history of Earth, this documentary will take you 445 million years into the past.
