Are you sure the end of the tail is preserved? To me, it looks like the tail
ends very suddenly, and could be broken and/or partly hidden in the

The shapes of the elements are terrible, but their topological relationships
are not all that bad.

The thing you identify as a quadrate ought to be one -- if not a pterygoid.
The thing cranial to it, though, is in the right position for a postorbital,
and contacts more or less the right bones.

Who would have told them to use crown, root and constriction instead of
corona, radix and cervix dentis. Of course, the goal of describing the teeth
in such detail is ABSRD.
I can't find the tail, BTW. I wonder if it's on the counterslab (which is
not figured and may not exist).
You could add the peculiar heterodonty to the diagnosis.
