If someone is telling you that they are "just plain old theropod teeth",
they are misinformed.
Spinosaurid teeth are much more oval in cross-section (mediolateral axis is
much wider compared to anteroposterior axis than in typical theropods).
The difference between baryonychine and spinosaurine teeth is that
spinosaurine teeth seem to be less curved, whereas baryonychines retain
something closer to the original theropod curvature in lateral view. They
remain, however, much rounder in cross-section than allosaur or ceratosaur
or whatever teeth of the same height.
