Biotic Recovery from Mass Extinction Events
In their discussions of the Late Ordovician graptolite near-extinction, both Melchin
& Mitchell (1991) and Koren (1991) indicated a need to know precise patterns of
graptoloid occurrences in the extinction interval on local and regional scales.

used the graptolite biozones (Fig. ... graptolite zonal sequence established and

Indeed, the graptolite extinctions are the most significant effects of the event,
eliminating some 95% of the species globally – a lower Homerian fauna of about
50 species was reduced to two or three in the basal upper Homerian (Melchin et
al.
