Exotic trilobites from the uppermost Cambrian Series 3 and lower Furongian of Sweden
(2015) In Acta Geologica Polonica 65(1). p.21-67- Abstract
- Seventeen taxa of exotic trilobites representing eight families are described from the olenid- and agnostoid-dominated strata of the uppermost Cambrian Series 3 and lower Furongian alum shale facies of Sweden and from glacial erratic boulders of Denmark. Only the taxa are assigned to species level, i.e., Maladioidella abdita (Salter, 1866), Olentella rara (Westergard, 1922), Pedinocphalus peregrinus (Henningsmoen, 1957), Ptychoparia pusilla (Westergard. 1922), and Westergaardella olenorum (Westergard, 1922), whereas the others are left under open nomenclature or remain unrecognized. Most are described for the first time from the Cambrian of Scandinavia. Their affinities point to a strong connection with East Gondwana, Laurentia,... (More)

Most are described for the first time from the Cambrian of Scandinavia. Their affinities point to a strong connection with East Gondwana, Laurentia, Kazakhstania and Siberia. Exotic trilobites appear in the succession directly after periods of very low oxygen concentration in the Alum Shale Sea; their occurrences correspond to the ranges of agnostoid arthropods in the succession and seem to be linked to global transgressive events causing an influx of cool mid or oxygen depleted waters onto the shelf of the Baltica palaeocontinent (Less)
