Figures

Fig. 2. Palaeanodon sp., MNHN QNY 2−275, from Le Quesnoy, SEM micrographs. A–C. Right lower jaw in occlusal (A), lingual (B), and labial (C) views; mb, medial buttress; pd, posterior diastema; pc5, last lower postcanine tooth (= m1); alpc4, alveolus for pc4 (= p4); img, internal mandibular groove. D. Detail of the infilling alveolus of pc4 in occlusal view, showing its elongated and laterally compressed outline which is suggestive of an elongated p4 with bilobed root (or possibly two−roots). A, B, D, stereo micrographs.

Fig. 3. Palaeanodon sp., right lower jaw MNHN QNY 2−275, from Le Quesnoy in occlusal (A) and lingual (B) X−ray views; alpc3, alveolus for pc3 (distal part); alpc4, infilled alveolus for pc4 (visible only in the higher part), the broad arrow indicates a dense transverse bony wall of the alveolus wall, probably indicating a bilobed root; pc5, m1; mb, medial buttress; mc, mandibular canal; pd, posterior diastema.
