Looking at it at 400 % magnification shows that you're right. The few
vertebrae near the end look much thicker than they are because of their long
chevrons, which the last vertebra lacks.

That's the ventral half of the postorbital. The broad and long "triangular
postorbital process of the frontal" is the dorsal half of the postorbital.

Oh! That ought to be it. :-)

The ilium is weird. Reminds me of a pachycephalosaur with its long pre- and
postacetabular blades.
