The Miguasha paleoestuary

A fresco of the ancient Miguasha estuary with the peaks of the young Appalachian mountain range in the background. The fish fauna were diversified, but it was Eusthenopteron foordi that dominated this watery world. Vegetation was concentrated along the shore, dense and tall enough in places to make forests.
