A newly studied Permian-Triassic (P-Tr) boundary section in Jameson Land, East Greenland, contains an abundant and well-preserved marine fauna as well as terrestrial palynomorphs. For the first time it is possible to compare the biotic crises of the marine and terrestrial realms using the same samples from the same section. The sediments record a negative excursion in δ 13 C carb values of 8‰–9‰, and in δ 13 C org values of 10‰–11‰. The presence of the conodont Hindeodus parvus, combined with… 
The terrestrial end-Permian mass extinction in South China
Refined Permian–Triassic floristic timeline reveals early collapse and delayed recovery of south polar terrestrial ecosystems
The collapse of late Permian (Lopingian) Gondwanan floras, characterized by the extinction of glossopterid gymnosperms, heralded the end of one of the most enduring and extensive biomes in Earth’s
Salinity changes and anoxia resulting from enhanced run-off during the late Permian global warming and mass extinction event
Abstract. The late Permian biotic crisis had a major impact on marine and terrestrial environments. Rising CO2 levels following Siberian Trap volcanic activity were likely responsible for expanding
Ecosystem remodelling among vertebrates at the Permian–Triassic boundary in Russia
TLDR
The nature of the event in Russia is document in a comprehensive survey of 675 specimens of amphibians and reptiles from 289 localities spanning 13 successive geological time zones in the South Urals basin, with a profound loss of genera and families and simplification of ecosystems.
Environmental crises at the Permian–Triassic mass extinction
The link between the Permian–Triassic mass extinction (252 million years ago) and the emplacement of the Siberian Traps Large Igneous Province (STLIP) was first proposed in the 1990s. However, the
Delayed recovery of non-marine tetrapods after the end-Permian mass extinction tracks global carbon cycle

TLDR
It is demonstrated that non-marine tetrapods were severely affected by the end-Permian mass extinction, and that these assemblages did not begin to recover until the Middle Triassic, consistent with the idea that unstable low-diversity post-extinction ecosystems were subject to boom–bust cycles.

TLDR
This fungal event can be considered to reflect excessive dieback of arboreous vegetation, effecting destabilization and subsequent collapse of terrestrial ecosystems with concomitant loss of standing biomass.
The delayed resurgence of equatorial forests after the permian-triassic ecologic crisis.
TLDR
The reconstructed pattern of vegetational change suggests that habitat restoration, migration, and evolutionary processes acted synergistically, setting the stage for successional replacement of lycopsid dominants by conifers within a period of approximately 0.5 million years.

In this text the demise of the dinosaurs is put into the proper context of other extinction events and all proposed extinction mechanisms - climate change, meteorite impact, volcanisms - are critically assessed.

TLDR
Biostratigraphic controls from strata intercalated with ash beds below the boundary indicate that the Changhsingian pulse of the end-Permian extinction, corresponding to the disappearance of about 85 percent of marine species, lasted less than 1 million years.
