Pluvia meteoritarum Ordovicia
Pluvia meteoritarum Ordovicia, Anglice Ordovician meteor event, media periodo Ordovicia accidisse constat, annorum 467.5 ± 0.28 milies milium ante praesentem. Meteoritae L chondritae fragmenta fuisse censentur magni asteroidis, eo aevo per collisionem destructi, cuius vestigia maiora fuerint asteroidae hodie noti 8 Flora et 433 Eros.

 
Proponitur ab hac dissolutione nubem spatialem evenisse qui severam glaciationem provocaverit, deinde et diversificationem specierum.
