Abstract
Early, Middle and Late Cambrian faunas from Peary Land, eastern North Greenland, are briefly documented. The Early Cambrian faunas of the lower Brønlund Fjord Group are assigned to the Bonnia-Olenellus Zone, although olenellids from the underiying Buen Formation may be older. Strata from the upper Brønlund Fjord Group with Middle Cambrian faunas are seemingly separated from the Lower Cambrian by a discontinuity, without representation of early Middle Cambrian zones. Faunas from lower beds of the overlying Tavsens Iskappe Group span the Middle-Late Cambrian boundary. Upper beds ofthe Tavsens Iskappe Group are assigned to the Late Cambrian, but corroborative faunal evidence is not yet available.
Highlights
Middle and Late Cambrian faunas from Peary Land, eastern North Greenland, are briefly documented
This paper results from a preiiminary examination of collections of Cambrian fossils obtained during the summer of 1978 in Peary Land, eastern North GreenJand, in the first year of a GGU regional geological mapping programme
Prior to 1978, the best known Cambrian sequence in Peary Land was at Jørgen Brønlund Fjord where Lower Cambrian sediments are unconformably overlain by dolomites of the Wandel Valley Formation of Late Canadian to Middle Ordovician age, (Jepsen, 1971; Christie & Peel, 1977)
Summary
TroeIsen (1956) reported a fauna including fragments of olenellids and SalterelIa from the base of the Brønlund Fjord Group near Midsommersøer (fig. l, locality 5). TroeIsen (1956) reported a fauna including fragments of olenellids and SalterelIa from the base of the Brønlund Fjord Group near Midsommersøer This material was briefly noted by Peel, Dawes & TroeIsen (1974) who, in addition, reported hyolithids, Pelagiella. Peel & Christie (1975) and Christie & Peel (1977) recognised this unit at Jørgen Brønlund Fjord The unit with its fauna of late Early Cambrian age has been recognised at several localities as far west as the Adams Gletscher area (Peel, 1979)
