Multiple cladistic analyses recognize the clade including Anadoluvius, Ouranopithecus, and Graecopithecus (graecopithecins) as stem hominines, but the origin of hominines remains unclear. Some analyses recover dryopithecins as stem hominines broadly ancestral to graecopithecins. Others recover dryopithecins as stem hominids, with the ancestry of graecopithecins more likely represented by Nakalipithecus. Here we investigate the morphology of the enamel-dentine junction (EDJ), a dental structure recognized as a reliable taxonomic and phylogenetic proxy. We analyzed the EDJ shape of maxillary and mandibular premolars and molars of Anadoluvius in comparison with other Eurasian Miocene apes, Plio-Pleistocene hominins (Australopithecus and Paranthropus), and extant great apes (Pan, Gorilla and Pongo) using geometric morphometrics. Our results indicate that Anadoluvius and Ouranopithecus show similar EDJ molar shapes, resembling both pongines and hominins, but differing from dryopithecin and African ape morphologies. However, dryopithecins also overlap with Pan, Pongo, and the hominins, sharing similar overall EDJ proportions and occlusal pattern, which complicates the interpretations of phylogenetic relationships. The EDJs of Anadoluvius premolars classify most commonly with Pan in comparisons with extant apes and variously with diverse hominids when fossil taxa were included. Our results support Anadoluvius and Ouranopithecus as closely related. Additional analyses including hominins and other Miocene apes are required to further clarify patterns of EDJ shape among hominines.
