Fig. 1 in What is 'Pseudo' in Pseudotribosphenic Teeth?

Fig. 1. Comparison of tribosphenic (a) and pseudo-tribosphenic (b) morphology for upper (top) and lower (bottom) molars, with basins and cusps labelled according to the nomenclature proposed here. The main upper cusps of both forms are labelled protocone, paracone and metacone, while the structures associated with the pseudotalonid basin on the lower are suffixed with 'pseudo'. (a) upper is Peramus and lower is unidentified lower from Crompton (1971), redrawn from Wang et al. (1998); (b) upper and lower are based on Pseudotribos, redrawn from Luo et al. (2007).
