Abstract

The uppermost Lower Silurian and Upper Silurian Gascons and West Point Formations of the southern Gaspé Peninsula were deposited under a broad range of environmental conditions from deep offshore-shelf to reef facies. Halysitid and auloporid tabulate corals occur in a number of facies and show a high degree of endemism.

Two species of Halysitidae and three species of Auloporida are found in these formations. Both halysitids have been previously described from this region. The auloporids include the new species Syringopora minuta and another species that may represent the first known Silurian occurrence of the fletcheriellid genus Pseudofletcheria. A neotype for the halysitid Cystihalysites amplitubulatus (Lambe) is proposed.
