H. G. Seeley 1895The occipital plate is usually concave. The parietal crest is narrow with large temporal vacuities, and a zygoma into which the malar bone enters. The anterior nares are terminal; the palato-nares are defined by a hard palate. The teeth resemble incisors, canines, and molar teeth odf mammals in form and position.
