Description
Original diagnose after Feichtinger et al. (2020) p. 828 [26760]: Teeth of Cretacladoides noricum gen. et. sp. nov. exhibit a high and slender main cusp with three pairs of lateral cusplets, the highest of the triplet is the middle cusplet. The acute cutting edges are continuous between the main cusp and the lateral cusplets, all cusps are strongly inclined lingually and are slightly sigmoidal in profile view. The labial crown face of the main cusp exhibits either a superimposed, triangular enameloid area or reduced ridges. Due to the elongated and acute cusps the teeth of C. noricum gen. et sp. nov. appear slightly fragile.

Remarks
valid after Feichtinger et al. (2020) p. 826 [26760];
