The spinosaurid dinosaurBaryonyx(Saurischia, Theropoda) in the Early Cretaceous of Portugal

Jaw fragments bearing teeth from the Barremian of Boca do Chapim (Lisboa e Setubal Province, Portugal), originally considered as crocodilian and identified as Suchosaurus girardi by Sauvage, are redescribed and referred to the spinosaurid dinosaur Baryonyx , on the basis of comparison with Baryonyx walkeri , from the Barremian of England. This extends the geographical distribution of this unusual theropod genus to Portugal. Baryonyx appears to have been a frequent component of Early Cretaceous dinosaur assemblages in the Iberian region, which may have formed a biogeographical ‘stepping-stone’ for baryonychine dispersal between Europe and Africa.
