The Furongian trilobite Irvingella from Jämtland and à ngermanland, Sweden

摘要

New material of Irvingella from central Sweden includes a cranidium of Irvingella major which is associated with fragmentary olenid trilobites that represent the Parabolina brevispina Subzone of the P. spinulosa Zone. This affords a direct correlation between the olenid trilobite zonation of Baltica and the Irvingella major Zone at the base of the Sunwaptan Stage in Laurentia. Several topotypic cranidia of Irvingella suecica Westergård confirm the features of that species but do not provide a direct indication of its position within the olenid zonal succession.View full textDownload full textKeywordsFurongian, Jämtland, à ngermanland, Sweden, Irvingella , correlationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/11035897.2010.529502
