Diagnosis
ReferenceDiagnosis
H. F. Ketchum and R. B. J. Benson 2011Longirostrine pliosaurid with seven autapomorphies: six, widely spaced premaxillary alveoli; teeth subcircular in cross-section with longitudinal enamel ridges that only extend to the base of the enamel on one axial tooth surface (i.e. either the mesial or distal surface, this cannot be determined from isolated teeth); squamosal bulb absent; paired posterior processes present on anterior cervical ribs; distal end of dorsal ribs expanded by rugose bone and subequal in diameter to the proximal end; undulating dorsal margin of scapular blade; clavicle with rod-like posterolateral process and two notches in its medial margin.
