Abstract Previous discussions of mass extinction mechanisms generally focused on circumstances unique to each event. However, some have proposed that extensive volcanism combined with bolide impact may offer a general mechanism of mass extinction. To test this hypothesis we compared generic extinction percentages for 73 stages or substages of the Mesozoic and Cenozoic. We found that the highest frequency of intervals with elevated extinction occurred when continental flood basalt volcanism and… 
The Alvarez Impact Theory of Mass Extinction; Limits to its Applicability and the “Great Expectations Syndrome”
For the past three decades, the Alvarez impact theory of mass extinction, causally related to catastrophic meteorite impacts, has been recurrently applied to multiple extinction boundaries. However,

TLDR
It is shown that if there is a periodic extinction signal at all, it is much more likely to result from a combination of a comparatively weak periodic cause and various random factors.
The sixth mass extinction: Anthropocene and the human impact on biodiversity
Mass extinctions are a major pattern in macroevolution. Because of their frequency, quickness and global effects, they shaped the global biodiversity several times during the geological ages. As an
Past, present, and future mass extinctions
Abstract Enigmatic catastrophic events, involving mass extinction of life forms, have been recorded several times in the Earth history. In many cases, the causes and mechanisms of these major and
A preliminary test of the press-pulse extinction hypothesis: Palynological indicators of vegetation change preceding the Cretaceous-Paleogene boundary, McCone County, Montana, USA
Many workers consider the Cretaceous-Paleogene extinction the archetypal catastrophic pulse event caused solely by the Chicxulub bolide impact. However, based on a global scale analysis of marine
Abiotic causes of the great mass extinction of marine biota at the Triassic-Jurassic boundary
In the interval of the Triassic-Jurassic boundary up to 80% of marine species became extinct. The main hypotheses on the causes of this mass extinction are reviewed. The extinction was triggered by a
Relationship between impact-crater size and severity of related extinction episodes
Abstract How large must an extraterrestrial impact be to cause a peak episode of increased extinctions of life? Impact energies ≥ 3 × 107 Mt TNT (associated with terrestrial impact craters with final
Comparison of the ages of large-body impacts, flood-basalt eruptions, ocean-anoxic events and extinctions over the last 260 million years: a statistical study
Many studies have linked mass extinction events with the catastrophic effects of large-body impacts and flood-basalt eruptions, sometimes as competing explanations. We find that the ages of at least
Time Scales of Critical Events Around the Cretaceous-Paleogene Boundary
TLDR
Radiometric dating establishes the mass extinction that killed the dinosaurs as synchronous with a large asteroid impact between the Cretaceous-Paleogene boundary and associated mass extinctions with the Chicxulub bolide impact to within 32,000 years.
Evolution caused by extreme events
TLDR
Several case studies of contemporary evolution in response to two types of extreme environmental perturbations, episodic (pulse) or prolonged (press).

Volcanism, impact and mass extinctions: incredible or credible coincidences?
Massive continental volcanism and/or bolide impacts are considered by many authors to have caused three major mass extinction events during the last 300 million years: the end-Permian, end-Cretaceous
Causes of mass extinctions
Both bolide impacts and  ood basalts have been suggested as the cause of major perturbations in the history of the biosphere, and the external (cosmic) and internal (Earth-bound) factors of mass

Mass extinctions: Persistent problems and new directions
TLDR
Difficulties in resolving the fine details of taxon ranges and abundances immediately prior to and after an extinction boundary and the scarcity of simple, unitary cause-and-effect relations in complex biological systems underlie these long-standing disagreements.

TLDR
Empirical studies reveal a more complex dynamic, including positive feedback and an exponential growth phase during recoveries, which is far from a model of refilling ecospace, which must be rebuilt during recovery.
