Biotic responses to the Late Devonian global events: Introductory remarks

Investigations of the Late Devonian successions have provided a great deal of evidence to support the hypothesis that the biospheric turning point near the Frasnian–Famennian (F–F) boundary was one of the most significant in Phanerozoic time. Considerable attention and debate have been focused on deter− mining the cause(s) of these biocrises, and various mechanisms have been proposed for the extinction of a wide range of benthic, primarily...
