What Conditions Accompanied the Late Ordovician Mass Extinction?
WebbDebates about the exact causes of the Ordovician-Silurian mass extinction are varied and speculative. As always, science is largely determined by the weight of evidence. The Late Ordovician mass extinction (LOME), sometimes known as the end-Ordovician mass extinction or the Ordovician-Silurian extinction, is the first of the "big five" major mass extinction events in Earth's history, occurring roughly 443 Mya. It is often considered to be the second-largest known extinction event, in terms of the percentage of genera that became extinct. Extinction was globa… WebbPeanuts!
