Brachiopod assemblages recorded in the Toarcian outcropping of the Asturian coast, between Gijón and Ribadesella, are described. In the Tenuicostatum Zone of the Early Toarcian, an assemblage dominated by Gibbirhynchia cantabrica nov. sp., which also includes some other species of North European affinities, has been recorded. Brachiopods disappear in the region at the end of this Zone, coinciding...

So far, 62 ammonite taxa have been recorded from this area, including 25 taxa from earlier studies. The taxa belong to the families Cymbitidae,...
