Llandovery trllobites from Washington Land, North Greenland

Abstract

Twenty-eight forms of trilobites obtained from a single block of Lower Silurian limestone are described. Three new species – Stenopareia somnifer, Cyphoproetus? alyo and Harpidella (Harpidella?) helenae – are erected. The fauna is considered to indicate an upper Lower Llandovery or lowest Middle Llandovery age; it is compared in particular with other faunas from similar lithology.
