Diagnosis
ReferenceDiagnosis
O. Rieppel 1995"Medium-sized to large eusauropterygians with a longirostrine skull, constricted snout, large and elongated upper temporal fossae, posteriorly displaced pineal foramen, paired fangs in the maxilla, enlarged fangs in the posterior symphyseal area of the lower jaw, lower jaw symphysis distinctly elongated and distinctly set off from lower jaw ramus, vertebrae platycoelous and non-notochordal with short and stout transverse processes."
O. Rieppel and R. Wild 1996Small to large eusauropterygians of the family Nothosauridae; maxillary tooth row extending well beyond level of anterior margin of upper temporal fenestra; paired maxillary fangs followed by a palisade of densely set, distinctly smaller, conical teeth; longitudinal diameter of the upper temporal fenestra between two and four times the longitudinal diameter of the orbit; never more than three ossifications in carpus or tarsus of adult.
