A new lower Cambrian eodiscoid trilobite fauna from Swedish Lapland and its implications for intercontinental correlation
A lower Cambrian eodiscoid trilobite fauna and an associated holmiid trilobite, Holmia sp., are described from a bioclastic limestone at the top of the Tornetr¨ask Formation in the Luob´akti section, south of Lake Tornetr¨ask, northern Sweden. Other associated polymerid trilobites include Orodes? la...
