Miguasha National Park is located within this formation along the estuary of the
Restigouche River on the south coast of the
Gaspé Peninsula. The fossil biota from the Park is thus referred to as the Miguasha biota. The main Miguasha exposures were named the 'René Bureau Cliffs' after the geologist and paleontologist. the actinistian
Miguashaia and the tetrapodomorph
Euthenopteron. The formation's depositional environment has been variously considered as
lacustrine,
estuarine, coastal marine or marine, though evidence from the fossil assemblage, stratigraphic and sedimentological setting, and geochemistry of the sedimentary rocks and bones suggests an estuarine interpretation is most fitting. ==Fossil content==
