The spinosaurid dinosaur Baryonyx (Saurischia, Theropoda) in the Early Cretaceous of Portugal
Abstract
Jaw fragments bearing teeth from the Barremian of Boca do Chapim (Lisboa e Setubal Province, Portugal), originally considered as crocodilian and identified asSuchosaurus girardiby Sauvage, are redescribed and referred to the spinosaurid dinosaurBaryonyx, on the basis of comparison withBaryonyx walkeri, from the Barremian of England. This extends the geographical distribution of this unusual theropod genus to Portugal.Baryonyxappears 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.
