A new lower Cambrian eodiscoid trilobite fauna from Swedish Lapland and its implications for intercontinental correlation

Axheimer, Niklas LU ; Ahlberg, Per LU and Cederström, Peter (2007) In Geological Magazine 144(6). p.953-961
Abstract
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? lapponica and Strenuaeva inflata. The precise age of the trilobite fauna cannot be determined,

but its generic composition and stratigraphical position at the top of the lower Cambrian suggest that it

was recovered from the Ornamentaspis? linnarssoni Assemblage Zone. Two species of eodiscoids are

present: Neocobboldia aff. dentata and Chelediscus acifer. The latter species is known previously... (More)

England and southeastern Newfoundland, and provides a novel link between upper lower Cambrian

successions in Baltica and Avalonia. (Less)
