Longrich et al. 2021

Xenodens is an extinct genus of mosasaurine mosasaurid known from the Late Cretaceous phosphate deposits in the Ouled Abdoun Basin of Morocco. The genus contains a single species, Xenodens calminechari, known from two isolated maxillae with unusual saw-like teeth. While some researchers have expressed uncertainty regarding the authenticity of the holotype specimen, additional remains and CT scans have supported the original identifications.
