Situated above the Vingeanne gorges, on the other side of the A31, this marsh was formed on an outcrop of marl, a curious, soft rock full of oyster debris. All you have to do is bend down near a puddle in the marsh to discover oyster shells, as well as terebratula and other brachyopods. These fossils remind us that the marshes of the Rosière marsh were formed at the bottom of a deep sea. The marshes also contain rare flora and fauna, such as the pneumon gentian and the butterfly that feeds on it.
