Bioestatigrafía del tránsito Triásico-jurásico en Asturias: ammonoideos y bivalvos entre Aviles y Caravia. (España)

The finding of ammonoids and bivalves in the deposits of the Triassic-Jurassic (T-J) transition in the Gijón Formation (Asturias) allowed improvement of the biostratigraphy and chronostratigraphy of the Rhaetian and the Hettangian. Among the ammonoids, the record of an Arcestidae ? (Rhae- tian) and...
