Evidence for the recovery of terrestrial ecosystems ahead of marine primary production following a biotic crisis at the Cretaceous–Tertiary boundary
The fossil record demonstrates that mass extinction across the Cretaceous–Tertiary (K–T) boundary is more severe in the marine than the terrestrial realm. We hypothesize that terrestrial ecosystems…
End-Cretaceous marine mass extinction not caused by productivity collapse
TLDR
A transient episode of surface ocean acidification may have been the main cause of extinction of calcifying plankton and ammonites, and recovery of productivity may have be as fast in the oceans as on land.
High-resolution organic carbon isotope record across the Cretaceous–Tertiary boundary in south-central Alberta: implications for the post-impact recovery rate of terrestrial ecosystems and use of δ13C as a boundary marker
A high-resolution study identified a δ 13 C excursion of -1.8‰ to -2.3‰ in terrestrial organic matter across the Cretaceous-Tertiary (K-T) boundary at two localities in the Scollard Formation of…
Chicxulub and climate: radiative perturbations of impact-produced S-bearing gases.
TLDR
Although the climate perturbation to the forcing appears to be relatively large, the geologic record shows no sign of a significant long-term climatic shift across the K/T boundary, which is indicative of a fast post-impact climatic recovery.

Analysis of pollen and spore assemblages from both terrestrial and near-shore marine sediments in New Zealand reveal an instant and dramatic mass-kill of the land plants in close association with the…
Paleobotanical Evidence for Climatic Change across the Cretaceous-Tertiary Boundary, North America: Twenty Years after Wolfe and Upchurch
A b s t r a c t In 1981 orth et al. (orth et al. 1981) provided the first micropaleontological evidence for terrestrial mass-mortality at the Cretaceous-Tertiary (or K-T) boundary associated with the…
Cenozoic mass extinctions in the deep sea: What perturbs the largest habitat on Earth?
Deep-sea benthic foraminifera live in the largest habitat on Earth, constitute an important part of its benthic biomass, and form diverse assemblages with common cosmopolitan species. Modern deep-sea…

The environmental disaster of Aznalcóllar (southern Spain) as an approach to the Cretaceous–Palaeogene mass extinction event
TLDR
The dramatic consequences of the K-Pg boundary impact and the generalized long-time recovery interpreted after the event could have been overestimated due to the absence of a high-temporal resolution in the range of 10(2)-10(3) years.

Organic carbon fluxes and ecological recovery from the cretaceous-tertiary mass extinction
TLDR
Under this hypothesis, marine production may have recovered shortly after the mass extinction, but the structure of the open-ocean ecosystem did not fully recover for more than 3 million years.

TLDR
Clay samples from three Cretaceous-Tertiary boundary sites contain a worldwide layer of soot, suggesting that soot production by large wildfires is about 10 times more efficient that has been assumed for a nuclear winter.
