Phylogenetic Clustering of Origination and Extinction across the Late Ordovician Mass Extinction.
PLoS ONE, 2015 Mass extinctions can have dramatic effects on the trajectory of life, but in some cases the effects can be relatively small even when extinction rates are high.

Shared patterns in body size declines among crinoids during the Palaeozoic extinction events
Scientific Reports, 2021 Crinoids were among the most abundant marine benthic animals throughout the Palaeozoic, but their body size evolution has received little attention. Here, we compiled a comprehensive database on crinoid calyx biovolumes throughout the Palaeozoic. A model

Euxinic ocean during the Late Devonian mass extinction inferred from organic compounds [PDF]
Journal of Earth Science, 2010 There were five mass extinctions of Earth life during the past 500 million years. The second crisis of the “big five” mass extinctions occurred near the Frasnian/Famennian (F/F) boundary in the Late Devonian. This extinction impacted mainly oceanic regime and resulted in 21% of families and 50% of genera among oceanic life being wiped out (Sepkoski ...

Insight into tube-building behaviour and palaeoecology of some agglutinating worms from the Upper Devonian of Nevada, USA [PDF]
, 2015 Agglutinated worm tubes from the Upper Devonian of the Devils Gate section in Nevada, USA are reported for the first time, filling a major gap in their Palaeozoic fossil record.

Gamma-ray spectrometry across the Upper Devonian basin succession at Kowala in the Holy Cross Mountains (Poland) [PDF]
, 2003 The Upper Devonian sequence at Kowala in the Holy Cross Mountains was logged using gamma-ray spectrometry, for investigating the changes of oxygenation level in the Late Devonian basin.

Geochemistry, Geophysics, Geosystems, 2023 Continental interiors were flooded by epeiric seas during many intervals of the geologic past. Few modern analogs exist for these environments, however, and basic variables such as redox, salinity, and restriction are difficult to reconstruct in deep ...

Large igneous provinces and mass extinctions: an update [PDF]
, 2014 The temporal link between mass extinctions and large igneous provinces is well known. Here, we examine this link by focusing on the potential climatic effects of large igneous province eruptions during several extinction crises that show the best ...
