Description:
Theropod teeth have long been known from the Upper Cretaceous of Europe, but the 20 million years long interval spanning the Cenomanian to the Campanian has remained underrepresented in the fossil record and understudied. Recent discoveries from the Turonian and Coniacian of Austria and the Santonian of Hungary fill this gap to some extent. Here we report on a study of 2D morphometry and dental wear of Turonian–Maastrichtian theropod teeth from Central Europe aimed at shedding further light on the phyletic and adaptive diversity of Late Cretaceous theropods in the archipelago of Europe. Our results suggest that the taxa Paraves indet. and Paronychodon were present in the region from the Turonian to the Maastrichtian, while medium-sized tetanuran forms are known only until the early Campanian. The record of some groups, such as troodontid or bird-like forms, is more sporadic and known only from a few sites. Dental wear study indicates that theropod teeth rarely show severe wear exposing dentin, though spalled surfaces are commonly seen on tetanuran teeth. Dental microwear feature and texture analysis of the worn enamel surfaces show a dominance of scratches (82–100%), with somewhat higher complexity in some of the non-serrated forms. The largest tetanuran teeth differ in terms of scratch length, pit size and anizotropy from the small, serrated Paraves indet. 1 teeth, but overlap with those of the extant carnivore-scavenger Varanus komodoensis suggesting large tetanurans resembled V. komodoensis in feeding on large vertebrates.
