To finally answer my own question, I've meanwhile received the book itself
to write a review. The troodontid teeth from the same place have much
smaller serrations only on the caudal edge and are much more strongly
recurved. While I am at it, the 103 cf. *Archaeopteryx* teeth from there
have very small rounded serrations only on the _anterior_ (that's called
labial, no?) edge (not prepared in the German specimens). The overall shape
of the teeth is laterally convex and strangely twisted, pointing at an
unknown specialisation (hint, hint?). An ilium referred to *Stokesosaurus*
has also been found in Guimarota.
