The stratigraphic continuity and good preservation of the Brachiopods in the section of Fuentelsaz (Province of Guadalajara, Spain), permit to carry out a detailed study of these fossils in the Toarcian-Aalenian transition. This study puts on evidence an episode of species renewal in the Aalensis Subzone, and another episode of morphological modification at the Base of the Buckmani Subzone, the Latter being more important from the stratigraphical point of view. In the transition from the Buckmani Subzone to the Opalinum Subzone no significative change is observed in the associations. © 1994.
