Diversificatio biotorum Ordovicia,Verbum "diversificatio" habes in Henrici Bateni Speculo (saec. XIII)  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 chondritarumHans-Peter Gail, Mario Trieloff, "Thermal history modeling of the L chondrite parent body" (1 Iulii 2019) apud arXiv.org pro Astronomy & Astrophysics severamque glaciationem.
