I would follow the name
of earliest precedence that was used to separate *Baryonyx* from
*Spinosaurus,* i.e., Baryonychidae.
That reminds me... Oliver Rauhut raised the specter that the type material
for _Spinosaurus aegyptiacus_ might be a chimera, with the jaw material and
vertebrae coming from separate animals. If this is the case, which element
will bear the name _Spinosaurus_?
