Abstract

Abstract A new species of olenid trilobites, Olenus henningsmoeni n. sp., is described from the Upper Cambrian Olenus/Agnostus (Homagnostus) obesus Zone of Kinnekulle and Billingen in Vastergotland, Sweden. It is closely comparable to O. gibbosus and O. transversas, but differs in having 19 thoracic segments with long pleural spines. The large number of thoracic segments may indicate that it was derived by peramorphosis. A species of Parabolina from the Olenus/Agnostus (Homagnostus) obesus Zone is figured.
