Devonian faunas of the Sainte-Hélène Island breccia, Montréal, Quebec, Canada
Early and Middle Devonian fossils from the Sainte-Hélène Island diatreme breccias are criticially reviewed and analyzed stratigraphically. They include marine benthic faunas of Helderberg, Oriskany, Schoharie, Onondaga, and Hamilton ages. Brachiopods are the most abundant fossils; significant corals...
