Middle Ordovician astrochronology decouples asteroid breakup from glacially-induced biotic radiations

The Middle Ordovician icehouse has been suggested to be sparked by extra-terrestrial dust associated with an asteroid break-up. Here, the authors use an astronomically calibrated timescale to decouple millennia-scale climate and biodiversity change from the meteorite shower 468.4 million years ago.
