Excavations in later Middle Pleistocene levels at the Bau de l'Aubesier, Vaucluse, France yielded a maxillary molar (M-1 or M-2; Aubesier 10) and a partial mandible from the left C, alveolus to the right condylar base lacking the coronoid process (Aubesier 11). Dentally they are similar to other later Middle Pleistocene Europeans in dental dimensions and variable taurodontism (Aubesier 10 but not Aubesier 11). The small Aubesier 11 mandible exhibits a retreating symphyseal profile with a minimal tuber symphyseos, an anterior marginal tubercle at P-4/M-1, the mental foramen at P-4/M-1-M-1, a modest retromolar space, no lingular bridging of the mandibular foramen, an enlarged superior medial pterygoid tubercle, a modest lateral condylar tubercle, and a mandibular notch crest that intersects the middle third of the condylar margin. All of these features fall within the ranges of variation of later Middle Pleistocene Neandertal lineage humans, and some are characteristic of Middle Pleistocene human mandibles in general. In addition, Aubesier 11 exhibits pervasive ante mortem alveolar resorption with apical abscesses, alveolar bone destruction, universal labial/buccal bone loss, ante mortem tooth loss (for greater than or equal to81-8% of preserved alveoli), a lingual alveolar fenestration, and two broken root apices with masticatory attrition. These lesions indicate significantly impaired masticatory function, the oldest specimen currently known with such a reduced degree of dental function but one of several Middle Pleistocene human remains with indications of serious abnormalities.
