has a short premaxilla with five teeth and numerous nutritive foramina.
the anterior border has a sharp postero-dorsal slope. the suture
with the maxilla is is almost vertical, and has a short posterior
process on the dorsal margin. The maxilla is large, and high towards
the anterior end. Sloping posteriorly with a large maxillary fenestra
is a prominant ascending process. In the maxilla are fifteen alveoli,
and the interdental plates ate fused. the teeth are labo-lingually
compressed and recurve poisteriorly, and only the apical half of
the anterior border and the whole length of the posterior border
is serrated, with 12 serrations per 5 mm. The roots make up three
quarters of the length of the tooth. The dentary is shallow and
pointed anteriorly, with a pointed anterior, a narrow symphyseal
region and an acute interdentary angle. to the anterior there are
numerous nutritive foramina.
cervical and dorsal vertebrae have prominant pleurocoels, the latter
also showing wide, stout neural spines, and the sacrum is fused
with solid centra. the caudals are elongate narrow waisted, with
those to the anterior possessing thin blade-like neural spines.
the posterior third of the caudal vertebrae have elongate prezygapophyses,
which overlap the preceding vertebrae by 80% of the length of the
has a distal expansion, and is fused to the shallow coracoid. The
ischia and the pubes have well defined obturator notches as opposed
to enclosed foramina, and the pubic boot is 70% the length of the
has an elongate fourth trochanter, and is situated on the internal
surface of the shaft, with an clearly defined ovalposterio-lateral
muscle scar. The tibia has a bulge behind the crist-fibularis, and
the fibula is slender. The pes has three functional toes, the ungual
showing a dorsal groove.
