| Resumen: |
Six new theropod teeth recovered trom the Blasi 1-3 sites (Upper Maastrichtian) in Arén (Huesca province, Spain) are described and added to the twenty six teeth already known from these and other five localities of Late Campanian-Early Maastrichtian age from the Arén and Tremp formations (Figuero1a 2, Fontllonga 6, L'Abeller, Montrebei and Vicari 4, Lleida province). Eleven theropod teeth morphotypes are recognised: one belonging to a big size theropod of indeterminate family (Theropoda indet.), one small Coelurosauria indet. with unserrated teeth, the enigmatic Euronychodon sp, and eight morphotypes of cf. Dromaesauridae indet. with different denticle morphology and serration density (which would represent four five different taxa). The tooth previously described in the Upper Campanian of Lleida as "Richardoestesia Like" could also be assigned to cf. Dromaeosauridae indet. Theropod diversity in our sites is apparently similar to that of the rest of Europe, and increases through the Campanian-Maastrichtian transition, although our small samples is biased towards the youngest sites. |
