Type: article
Abstract: The fauna preserved in decalcified sandstones of the Sæterdal Formation (Cambrian Stage 4) of southern Peary Land, North Greenland (Laurentia) is dominated by the trilobites Kootenia marcoui and Bonnia brennus, which also occur in the equivalent dark carbonates and mudstones of the Henson Gletscher Formation to the west. They are associated with Olenellus and small ptychoparioid trilobites. Brachiopods compared to Nisusia ancauchensis, originally described from the Precordillera terrane in Argentina, show variation in shell morphology and the form of the pseudodeltidium. They occur together with Kutorgina cf. cingulata, which is conspicuous in the overlying Paralledal Formation, rare Matutella sp. and an indeterminate hyolithid.
