We present evidence of late Berriasian sedimentation which records the presence of Spiticeras correardi, whose stratigraphic range is not well established. Located at Cuencamé de Ceniceros, Durango State, northern Mexico, a section belonging to the Taraises Formation is here presented to show our results. Furthermore, the sampled ammmonite assemblage —herein constituted by Fauriella cf. boissieri, Berriasella cf. calisto, Spiticeras correardi, and Kilianiceras praegratianopolitense— is attributed to the upper Berriasian standard Mediterranean ammonite Zone Fauriella boissieri. It is worth noting that B. cf. calisto has strong biostratigraphic significance, due to the fact that it is restricted to the upper part of the aforementioned Fauriella boissieri Zone (Tirnovella alpillensis and Thurmanniceras otopeta subzones).
