Description
Diagnosis after Carrillo-Briceño, Stössel, Kindlimann & Klug, 2025 [34842]: Hybodontiform shark-like chondrichthyan species with a crushing-type dentition distinguished by the following features: (1) high degree of crown heterodonty between anterolateral and lateral teeth. (2) anterolateral teeth with subtriangular shape, lacking occlusal crest and characterized by a reticular ornamentation with well-defined folds that descend from the domed crown. (3) lateral teeth of the second lateral file with a subrectangular shape and wider mesio-distally than labio-lingually. The crown is high, slightly domed in the mesial part and lacking an occlusal crest, with an ornamentation that consists of a finely pitted reticulated pattern on most labial sections of the crown, which turn into numerous strong parallel folds labio-lingually aligned along the lingual section of the crown. Labial border is vertical and the lingual one inclined and shorter, and the root is high with a flat base.
