Description
Original diagnosis after Carrillo-Briceño & Cadena, 2022 [30751]: Species characterized by a typical crushing-type dentition with the following features: (1) Anterolateral teeth with a domed crown and a sub-rhomboidal shape in occlusal outline with vertical edges around their outline ornamented with irregular vertical ridges; (2) Relatively short lateral teeth (in comparison with other Jurassic species) with a parallelogram shape in occlusal outline, slightly domed in mesial section, with a pointed and lingually oriented mesial extremity, and labial and lingual vertical edges around their outline ornamented with irregular vertical ridges; (3) Anterolateral and lateral teeth with an occlusal ornamentation characterized by a reticulated pattern finely-pitted and without a crest.
