nal process peaks at region of styloid process, sepa-
rated from mastoid process (Ng l, Ng 6, Ng 7, Ng 13,
Ng 14); fades out before meatus (Ng 1, Ng 7, Ng 12);
goes to meatus (Ng 13, Ng 14). Articular fossa deep,

veloped (Ng 3)) tall s/i (Ng 6)) bulky, contained (Ng

plane: approximately 45" (Ng 5, Ng 6, Ng 12); more
horizontal (Ng 1, Ng 13); steep (Ng 3). Occipital
torus defined inferiorly by undercutting of nuchal
plane (Ng 1, Ng 3, Ng 5, Ng 6, Ng 12, Ng 13, Ng
14). Superior surface of petrosal: smooth/gently
curved (Ng 6, Ng 12, Ng 13); low arcuate eminence
(Ng 7); expansive, but not salient arcuate eminence
(Ng 14); all lack subarcuate fossa. Frontal lobes not
fully over orbital cones (Ng 1, Ng 5, Ng 6, Ng 14); Ng
12 not fully, but slightly more than others. Frontal
crest long (Ng 1, Ng 6, Ng 12, Ng 14); Ng 5 long, but
not as long as others. Middle branch of middle
meningeal artery notably arborized (Ng 4, Ng 6). In-
ternal occipital protuberance low lying (Ng 1, Ng 5,
Ng 7, Ng 12, Ng 13, Ng 14). Sutures undifferentiated,
poorly interdigitated (Ng 1, Ng 3, Ng 5, Ng 6, Ng 7,
