So I should be thankful it's not terrible in both ways, like Hou's Jibeinia
skeletal reconstruction? ;-)

If you mean the narrow strip roughly connecting the distal quadrate with the
broad triangular postorbital process of the frontal, I agree. But this is
far more delicate than the huge postorbital identified by Gong et al., which
seems to be what I call a quadrate (Gong et al. and I agree on
identification of the supratemporal fenestra).

Why not the structure directly ventral to the distal upper tibiotarsus, or
the structure ventral and perpendicular to that?

True, and I need to replace "maxilla" with "dentary", since it was a typo of
Gong et al. to state it had more than twenty-one maxillary teeth.
