Evidence for atmospheric carbon injection during the end-Permian extinction

Elke Schneebeli-Hermann et al., Palaeoecology, Laboratory of Palaeobotany and Palynology, Utrecht University, Budapestlaan 4, 3584 CD Utrecht, Netherlands. Posted online ahead of print of 26 March 2013; http://dx.doi.org/10.1130/G34047.1.

One of the big five mass extinction in Earth's history occurred at the end of the Permian, about 252 million years ago. The enormous loss of biodiversity was accompanied by a profound perturbation of the carbon cycle. Because land plants incorporate ambient atmospheric CO2 into their tissues during photosynthesis, fossil cuticle and wood fragments can be used to investigate ancient changes in atmospheric carbon isotope composition. Fossil plant tissue samples from a Permian-Triassic boundary section in Pakistan have been investigated. The data show that the carbon isotope composition of atmospheric CO2 dropped by ~5.5 parts per million close to the Permian-Triassic boundary. This profound change in atmospheric carbon isotope composition is synchronous with the end-Permian mass extinction. It indicates the input of a large amount of isotopically light CO2 into the atmosphere, directly or indirectly associated with the Siberian Trap volcanism.
