The Subcommission on Permian Stratigraphy (SPS) hasalways had very active working groups that consider challengesand opportunities that the Permian community thinks areimportant. At present there are three working groups in SPS.The Artinskian-base and Kungurian-base GSSP Working Group,the Carboniferous-Permian-Early Triassic Nonmarine-MarineCorrelation Working Group and the Correlation between marineand continental Guadalupian Working Group.At recent meetings of the SPS, it was considered that achallenge for Permian science is the difficulty of correlatingbetween Gondwana and Euramerica. This is particularly acutewhen important Gondwana successions are to be correlated withthe ‘standard sections’ (including GSSPs) in Russia, the US andChina. The SPS Executive therefore recommended that a WorkingGroup be set up and a list of possible members was suggested.The Working Group was first convened on 17th May with most ofthe suggested members present. A second meeting was held on17 June when all members were present. The group has agreedto have meetings around every two months or so to begin with,but also encourages meetings of sub-groups, for example, ofpalynologists, conodont specialists or brachiopodologists. Thegroup has tried to maintain a good balance of men and womenand representation of the main Gondwana and Euramericacontinents.
