Abstract

Ceratopea unguis is described from the Nunatami Formation of Washington Land, western North Greenland, confirming a late Canadian (Iate Early Ordovician) age. A correlation is thus established between the Nunatami Formation and the Wandel Valley Formation of Peary Land, eastern North Greenland, which also yields C. unguis.

Highlights

During the 1976 field season in western North Greenland, Peel collected abundant specimens of Ceratopea from the Nunatami Formation at Nygaard Bugt, Washington Land
This is the third locality in Greenland for the Early Ordovician gastropod, which is best known from its claw-like operculum
The Washington Land specimens are identified as Ceratopea unguis Yochelson & Bridge, 1958 and the record ofthis species is significant in establishing a correlation between the Nunatami Formation and the Wandel Valley Formation, almost 600 km to the east, and to outcrops in the U.S.A

Summary

Introduction

During the 1976 field season in western North Greenland, Peel collected abundant specimens of Ceratopea from the Nunatami Formation at Nygaard Bugt, Washington Land (fig. 1). During the 1976 field season in western North Greenland, Peel collected abundant specimens of Ceratopea from the Nunatami Formation at Nygaard Bugt, Washington Land Troeisen (1949) reported Ceratopea from the Wandel Valley Formation of Peary Land, eastern North Greenland
