Geochronological study finds tempo of late Ordovician mass extinction controlled by rate of climate change

The "Big Five" mass extinctions of the Phanerozoic Eon have long attracted significant attention from the geoscience community and the public. Among them, the Late Ordovician Mass Extinction (LOME) is the earliest of the Phanerozoic, and questions about its causes and dynamics have been a central focus in Earth sciences over the past century.
