Dimorphism and endemism in Hebetoxyites (Ammonoidea, lower Bajocian) from the Iberian Range (Spain)

New findings of lower Bajocian, haploceratid ammonites (Cephalopoda, Mollusca) of the genus Hebetoxyites from the Albarracín area are described and revised alongside specimens previously collected from the Iberian Range. Three species have been identified: H. hebes Buckman, H. incongruens Buckman an...
