Resumen de Theropod pedal unguals from the Late Cretaceous (Cenomanian) of Morocco, Africa
Fernando E. Novas, Fabio Dalla Vecchia, Diogo Pais
Two different theropod pedal unguals from the Upper Cretaceous (Cenomanian) of Tafilalt, Moroccoare described. One of them belongs to a slender kind of abelisauroid theropod. Comparison with other membersof this group reveals that abelisauroid unguals show high morphological diversity in congruence with what isknown on other parts of the skeleton. Another large-sized ungual resembles that described as “Spinosaurus B”by Stromer (1934), and is here referred with caution to Theropoda, although ignoring to which theropod lineageit belongs. Comparisons between northern (e.g., Sahara, Africa and Brazil) and southern (e.g., Patagonia)Gondwanan Cretaceous dinosaur faunas reveal some differences leading to the conclusion that Gondwananfaunas were not uniform across this supercontinent.
