Fig. 2. Overgrowth type 1 in Pathological phalanges in a camarasaurid sauropod dinosaur and implications on behaviour

Fig. 2. Overgrowth type 1 (arrow) in left pedal ungual I of the camarasaurid sauropod SMA 0002 from Upper Jurassic Morrison Formation, HoweStephens Quarry, Wyoming, USA; in lateral (A), dorsal (B), and proximodorsal (C) views. Note the dorsal position of the overgrowth on the proximal articular surface, and how it fits in the notch in the distal articular surface of php I-1 (C, slightly displaced taphonomically). Abbreviations: mt, metatarsal; php, pedal phalanx. Not to scale, the proximodistal length of php I-1 is 45 mm.
