Fig. 67. Holotype basicranium of Mammacyon obtusidens (ACM 34-41) with the remnant of the ectotympanic auditory bulla (T) in life position. The posterior portion of the bulla was lost but contacted the medial margin of the promontorium (P), evidenced at that location by a shallow depression (indicated by dashed line on inset).
