Partial
skull, the remains of 28 vertebrae, partial femora and an astragalus.
The skull is 4 cm long and consists of a partial left maxilla with the
distal ends of both dentaries attached. A fragmentary premaxilla lies
adjecent to the distal tip of the maxilla.
The
rostroventral margin of the antorbital fenestra lacks a well-marked
ventral margin. The dentary rami and slander, and the teeth are slender
and conical mesially and larger and laterally compressed distally;
there appear to be no marginal serrations, as so commonly seen on
theropod teeth. The vertebrae are poorly preserved, similar in form to
other theropods.
The dorsals are small,
cylindrical, and amphiplatyan, and the bases of the neural arches are
excavated but lack pleurocoels. Two caudals are described and
indentified becoase of their chevron facets.
The
femoral head is strongly inturned, the lesser trochanter is positioned
low (one quarter of the way down shaft), and the fourth trochanter is
large and crested. lying on the mediocaudal side of the shaft. The
astragalus is low and hemicylindral, with a low ascending process.
