Abstract

Archaeocyaths of the class Regulares have been discovered in the Devils Cove Member of the Forteau Formation in eastern and southern parts of western Newfoundland. The three species recovered are the first Regulares reported from the northern Appalachians, all archaeocyaths from the bioherms and biostromes to the west and north in Newfoundland and Labrador are Irregulares. This sparse, but well-preserved fauna is similar to the poorly-preserved fauna from the central and southern Appalachians, as well as the abundant and diverse Regulares fauna from the Cordillera, but unlike contemporaneous asiatic and australoantarctic faunas, lending support to the view that late Lower Cambrian archaeocyaths in North America were endemic.
