Unfortunetly, a mass extinction took place near the end of the era and destroyed as much as 95% of the ocean life.The first known major mass extinction event occurred during the Ordovician Period of the Paleozoic Era on the Geologic Time Scale. At this time in the history of Earth, life was in its early stages.
