Diversificatio biotorum Ordovicia
Diversificatio biotorum Ordovicia, Anglice aut Ordovician radiation aut great Ordovician biodiversification event, est multiplicatio specierum novarum quae media periodo Ordovicia accidisse constat, circa annorum 465 milies milium ante praesentem, post magnam pluviam meteoritarum L chondritarum severamque glaciationem.
