Land-plant diversity and the end-Permian mass extinction
@article{Rees2002LandplantDA, title={Land-plant diversity and the end-Permian mass extinction}, author={P. McAllister Rees}, journal={Geology}, year={2002}, volume={30}, pages={827-830} }
The Permian and Triassic represent a time of major global climate change from icehouse to hothouse conditions and significant (∼25°) northward motion of landmasses amalgamated in essentially one supercontinent, Pangea. The greatest of all mass extinctions occurred around the Permian-Triassic boundary (251 Ma), although there is no consensus regarding the cause(s). Recent studies have suggested a meteor impact and worldwide die-off of vegetation, on the basis of sparse local observations…

Evidence from correlative nonmarine strata elsewhere in the world containing fluvial Permian-Triassic boundary sections suggests that a catastrophic terrestrial die-off of vegetation was a global event, producing a marked increase in sediment yield as well as contributing to the global delta(13)C excursion across the Permians-Tri Jurassic boundary.
