Abstract

Halysitid tabulate corals occur in the Silurian and Devonian rocks of northeastern Gaspé Peninsula, Québec. Silurian specimens from the Dartmouth River and Madeleine River areas are referred to Cystihalysites. A specimen from a possibly Early Devonian level in the Gascons Formation in the Dartmouth River area is assigned to Cystihalysites. Two specimens from different levels in the Early Devonian part of the West Point Formation in the Madeleine River area are assigned questionably to Quepora. The latter occurrences in the West Point Formation demonstrate that this group of tabulate corals lingered into the Devonian.
