I still declare there are no teeth in *Scansoriopteryx*.
Are you saying there were no teeth preserved, or no teeth whatsoever?
Problematically, a maxilla is absent in both specimens, and
in *Epidendrosaurus*, several well-defined teeth (not bumps) are present in the rostral half of the dentary, and without utilizing Adobe to examine a less-than-ideal photograph, one can only trust
the opinion of the authors.
It's quite odd they did not offer a detailed photograph.
