Table 4. Occlusal shearing contacts between the opposite molars of Abdounodus hamdii during the power stroke of mastication as identified from occlusal sketches (Fig 5) and from 3D simulation of occlusion with the OFA software.

Shearing occlusal contacts	Upper molars (MHNM.KHG.154)	Lower molars
1	Anterior side of paracone (preparacrista) and protocone (preprotocrista)	Posterior side of protoconid and metaconid (protocristid)
2	Posterior side of metacone (postmetacrista) of opposite anterior upper molar	Anterior side of protoconid (paracristid, labial part) of opposite posterior lower molar
3	Posterior side of paracone (postparacrista)	Mesial side of cristid obliqua
4	Anterior side of metacone (premetacrista)	Posterior side of hypoconid (postcristid)
5	Lingual side of protocone	Anterior side of entoconid and hypolophid (lingual segment)
6	Posterior side of protocone	Posterior side of entoconid and hypolophid (lingual segment)
7	Anterior side of metaconule (pseudohypocone)	Posterior side of entoconid and hypolophid (lingual segment)
8	Posterior side of metaconule (postmetaconule crista)	Mesial side of postentoconulid and hypoconulid (postcristid)
