The Upper Devonian (Frasnian) Escuminac Formation from the Miguasha National Park is world renowned for its well-preserved and diverse fossil fish assemblage. It has also been the subject of continuous debate concerning its depositional environment, variously considered lacustrine, estuarine, and coastal marine. For the first time, foraminifera and thecamoebians have been identified in this formation. The presence of both foraminifera and thecamoebians suggest a brackish-water estuary environment.
