 The angular is medially excavated by the mandibular fenestra, and forms a vertical contact zone with the dentary; at the posterior end, it is vertically expanded upwards to form a narrow blade.The dentary carries three teeth on the preserved portion, which closely resemble those on the maxilla.The teeth are noticeably heterodont in "Adamantinasuchus", with a mixture of incisiform, caniniform and molariform teeth.
