First occurrence of family Clavatoraceae (fossil Charophyta) in the Middle Jurassic (Bathonian) of France

A rich and diverse charophyte flora is described from the Bathonian marginal marine beds of southern France.It includes nine species that belong to the families Porocharaceae, Characeae and Clavatoraceae: Porochara gr. fusca, P. gr. kimmeridgensis subgr. kimmeridgensis, P. gr. kimmeridgensis subgr....
