Dear Colleagues,

I am helping to organize a session on the Permian-Triassic biotic transition for the Joint GSA-GSC meeting in Chengdu, China, June 17-19, 2013.  There are also several other paleo-relevant sessions that may be of interest to members of this list.  Please feel free to spread the word.

C-2: Mass extinction at the Permo-Triassic boundary and subsequent recovery dynamics

Conveners: YIN Hongfu (UGS-Wuhan), PAYNE Jonathan (Stanford), SHEN Shuzhong (Nanjing Institute)

The mass extinction event at the end of the Permian Period eliminated a greater fraction of animal diversity than any event in the past 500 million years. The extinction and subsequent recovery dynamics also permanently altered the taxonomic composition and ecological structure of the biosphere. Many of the best paleontological records of extinction and recovery derive from stratigraphic sections in China and these have increasingly been coupled with high resolution studies of geochemical proxies that help to place biotic events within their local and global environmental contexts. This session will address patterns and processes of extinction and recovery from paleontological, sedimentary, geochemical, and geochronological perspectives. Particularly encouraged are contributions that seek an integrated biological and environmental understanding of extinction and recovery dynamics, and that highlight the ways in which this past catastrophe may help to inform our understanding of 21st century global change.
