Late Frasnian mass extinction: Conodont event stratigraphy, global changes, and possible causes
, 1988 Several abrupt changes in conodont biofacies are documented to occur synchronously at six primary control sections across the Frasnian-Famennian boundary in Euramerica. These changes occurred within a time-span of only about 100,000 years near the end of
