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.
Silurian successions, lithofacies and biostratigraphy In this chapter, we have
used the graptolite biozones (Fig. ... graptolite zonal sequence established and

Wes Gibbons, Teresa Moreno (Ph. D.), Geological Society of London, 2002
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.

The abundance changes that are associated with graptolite species turnover in
the Late Ordovician suggest an inverse sampling artifact could cause a gradual
