This photo shows some of the invertebrate animals that lived in the Lower Devonian brackish waters of the Gaspé region. This fauna consisted of the bivalve Modiolopsis, the inarticulate brachiopod Lingula (L), and the articulate brachiopod Globithyris (G). The remains of fish are often found with this association. The absence of such marine taxa in the invertebrate fauna of the Escuminac Formation explains why the idea of Miguasha as a freshwater lake held for so long. This specimen comes from the Cap-aux-Os Member of the Battery Point Formation.
