Description
Diagnosis after CASE & CAPPETTA, 1997 [401]: Rostral teeth of a Sclerorhynchus design but with a well differentiated posterior barb a little bit above the basal bulge. Oral teeth very low, with a cusp strongly bent lingually. Labial face very developed and bearing some radiating folds some of them dividing before the labial margin. Root slightly higher than the crown; root lobes wide with a flat basal face. There is a pair of large margino-lingual foramina.

Some authors described rostral spines in open nomenclature as Sclerorhynchus cf. pettersi, eg. Smith (1999) [2244] and Smith et al. (1999) [3462] from Belgium or Case et al. (2017) from the Peedee Formation of North Carolina, USA [25344]
