%X Six new theropod teeth recovered trom the Blasi 1-3 sites (Upper Maastrichtian) in Arén (Huescaprovince, Spain) are described and added to the twenty six teeth already known from these andother 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 theropodteeth morphotypes are recognised: one belonging to a big size theropod of indeterminatefamily (Theropoda indet.), one small Coelurosauria indet. with unserrated teeth, the enigmaticEuronychodon sp, and eight morphotypes of cf. Dromaesauridae indet. with different denticlemorphology and serration density (which would represent four five different taxa). The tooth previouslydescribed in the Upper Campanian of Lleida as "Richardoestesia Like" could also be assignedto cf. Dromaeosauridae indet. Theropod diversity in our sites is apparently similar to that of therest of Europe, and increases through the Campanian-Maastrichtian transition, although our smallsamples is biased towards the youngest sites.
