Abstract The Phanerozoic history of life has been interrupted by at least 17 different stage-level episodes of elevated extinction intensity. These range from major turnovers that affected the majority of the Earth’s extant biota (e.g. the Tatarian, Ashgill, and Maastrichtian events) to much smaller and perhaps more geographically localized disruptions. Review of available stage-level stratigraphic evidence suggests that bolide impacts do not exhibit a compelling correspondence to the…

Accelerated biotic turnover during the Late Triassic has led to the perception of an end-Triassic mass extinction event, now regarded as one of the ‘‘big five’’ extinctions. Close examination of the

Abstract The association between mass extinction in the marine realm and eustatic sea-level change in the Mesozoic is well documented, but perplexing, because it seems implausible that sea-level

Radiations and Extinctions of Maastrichtian Rudist bivalve and Benthic Foraminifera of Aqra Formation Kurdistan Region Northern Iraq
During the Maastrichtian, the rudists and benthic foraminifera of Aqra Formation underwent two major radiations, the first beginning in early Early Maastrichtian and peaking in the late Early
Impacts, volcanism and mass extinction: random coincidence or cause and effect?
Large impacts are credited with the most devastating mass extinctions in Earth's history and the Cretaceous – Tertiary (K/T) boundary impact is the strongest and sole direct support for this view. A


Flood basalts and extinction events
The largest known effusive eruptions during the Cenozoic and Mesozoic Eras, the voluminous flood basalts, have long been suspected as being associated with major extinctions of biotic species.
Extinction and survivorship of southern Tethyan Benthic foraminifera across the Cretaceous/Palaeogene boundary
Abstract The benthic foraminiferal record from the Cretaceous/Palaeogene boundary stratotype of El Kef, Tunisia, shows a succession of three distinct assemblages. The late Maastrichtian upper bathyal
Biogeography of cretaceous/tertiary (k/t) planktic foraminifera
As a result of the process‐level connections between biogeography, systematics, and ecology, analyses of the spatial distribution of organisms across major extinction events can be used to probe the

Taxa and adaptations can be lost not because they were poorly adapted by the standards of the background processes that constitute the bulk of geological time, but because they lacked--or were not linked to--the organismic, species-level or clade-level traits favoured under mass-extinction conditions.

Ammonoid extinction events
The ammonoid cephalopods range from the early Devonian to the late Cretaceous, a period of some 320 Ma. Because of their importance for biostratigraphic discrimination and their use in practical age
Taxonomic selectivity and continuous variation in mass and background extinctions of marine taxa
It is shown that except for the late Permian event, mass-extinction rates for each taxon were often not higher than many of their 'normal' background rates evincing continuous variation between them.
The Cretaceous-Tertiary biotic transition
Mass extinctions are recognized through the study of fossil groups across event horizons, and from analyses of long-term trends in taxonomic richness and diversity. Both approaches have inherent
