It was assigned to Mosasauridae by McDowell and Bogert (1954) and Carroll (1988); to Squamata by Sepkoski (2002); and to Tylosaurinae by Russell (1967), Novas et al. (2002), Bardet et al. (2005), Lindgren (2005), Hornung and Reich (2015), Hornung et al. (2018), Driscoll et al. (2019) and Rempert et al. (2022).

Diagnosis
ReferenceDiagnosis
J. Lindgren 2005"See Russell (1967)"; "Marginal teeth markedly compressed labiolingually. Lateroposterior marginal crowns nearly symmetrically bicarinate. Anterior and posterior carinae on lateroposterior marginal teeth pronounced from apex to base of crown. Carinae on pterygoid teeth minutely serrated. Proximal part of neural arch and transverse processes on caudal vertebrae thin. Vertebral centrum of pygals and anteriorly situated intermediate caudals proportionally short and broad. Interarticular surfaces on pygals and anteriorly situated intermediate caudals roughly triangular in outline and wider than high."
