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 ...
Earth’s first mass extinction: When anyone thinks of mass extinction on Earth, the first thing they think of is the extinction of dinosaurs about 66 million years ago, likely as an impact of comet or ...
Over half a billion years ago, during the Cambrian geological period, life on Earth started to get a lot more interesting. Thanks to the rise in free oxygen generated mostly by photosynthesizing algae ...
