North Atlantic temperature and pCO2 coupling in the early-middle Miocene
Evidence for abrupt speciation in a classic case of gradual evolution
A combination of morphological data and biostratigraphic evidence suggests that G. tumida evolved by cladogenesis, one of the best-documented cases of within-lineage phyletic gradualism, and revisit the limitations and promise of the study of speciation in the fossil record.
On impact and volcanism across the Cretaceous-Paleogene boundary
Carbon cycle modeling and paleotemperature records are used to constrain the timing of volcanogenic outgassing and found support for major out gassing beginning and ending distinctly before the impact, with only the impact coinciding with mass extinction and biologically amplified carbon cycle change.
A role for chance in marine recovery from the end-Cretaceous extinction
An analysis of the recovery of marine pelagic communities from the Cretaceous–Palaeogene mass extinction supports a model of contingent recovery, rather than one based on trophic structure.
Diverse patterns of ocean export productivity change across the Cretaceous-Paleogene boundary: New insights from biogenic barium
 One of the best-studied aspects of the K-Pg mass extinction is the decline and subsequent recovery of open ocean export productivity (e.g., the flux of organic matter from the surface to deep…

It is shown that the impact caused rapid ocean acidification, and that the resulting ecological collapse in the oceans had long-lasting effects for global carbon cycling and climate, and insights into the drivers of the last mass extinction, the recovery of marine carbon cycling in a postextinction world are provided.
Rarity in mass extinctions and the future of ecosystems
It is shown that the rarity of previously abundant taxa may be more important than extinction in the cascade of events leading to global changes in the biosphere, which may provide the most robust measure of the current biodiversity crisis relative to those past.
A probabilistic assessment of the rapidity of PETM onset

An Earth system model and a sediment-mixing model are employed and the likely PETM onset duration is extracted to show how changes in the relative population sizes of calcareous plankton, combined with sediment mixing, can explain the observations.
