FIGURE 1. Area of study in the Alcoy Basin, highlighting the main geological subdivisions of the Betic Range (above), and location of the El Muro, Bancales, and Castillo Barchell fossil sites referenced in the present study, as well as the Moli Palla locality for some of the fossils from the “Museo Paleontológico y de las Ciencias Isurus (Alcoy).”

FIGURE 4. Depth estimation employing weighted bootstrap analysis of the elasmobranch faunal composition, considering both A, the members of Batoidea, and B, and excluding them. The mean depth estimation is represented by the line, while the 95% confidence interval for the most probable depth range of the assemblage is illustrated as a shadow.
