I agree that the _Baryonyx_-_Suchomimus_ link suggests a trans-Tethys 
dispersal.  But this might have been an isolated event.  Overall, the north 
African and European dinofaunas do not show a lot in common during the Early 
Cretaceous.  For example, it's not even close to the degree of similarity 
shared by the Morrison, Tendaguru, and Lourinha/Alcobaca faunas of the Late 
Jurassic.

Yes, true.  But how confident are you in assigning dromaeosaurid teeth at the 
"subfamily" level?  :-)
