Abstract
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.

Keywords: Cretaceous, Portugal, dinosaurs, Theropoda, biogeography.

euenantiornithine birds from the Cretaceous of southern France, North  
America and Argentina. Geological Magazine, Published online by

Abstract ? We review historical approaches to the systematics of  
Enantiornithes, the dominant birds of the second half of the Mesozoic,  
and describe the forelimb remains of a new Cretaceous  
euenantiornithine. This taxon is known on the basis of fossil  
specimens collected from southern France, Argentina and the United  
States; such a wide geographical distribution is uncharacteristic for  
Enantiornithes as most taxa are known from single localities. Fossils  
from the Massecaps locality close to the village of Cruzy (H´erault,  
southern France), in combination with elements from New Mexico (USA)  
and from the Argentine locality of El Brete (Salta Province) testify  
to the global distribution of large flighted euenantiornithine birds  
in the Late Cretaceous.We discuss the systematics and taxonomy of  
additional isolated bones of Enantiornithes that were collected from  
the Argentine El Brete locality in the 1970s; the presence of these  
flying birds in Cretaceous rocks on both sides of the equator, in both  
northern and southern hemispheres, further demonstrates the ubiquity  
of this avian lineage by the latter stages of the Mesozoic.
