Cenomanian dinosaur tracks on the islet of Fenoliga in southern Istria, Croatia

Abstract

One hundred and forty six dinosaur footprints occur on the Cenomanian outcrop of Fenoliga. They are arranged in six trackways and six footprint groups (a–f). Two basic footprint types can be distinguished: firstly, large circular-elliptical sauropod footprints, forming four trackways (I, III, V, VI) and five footprint groups (a–e), and secondly, smaller, tridactyl theropod footprints forming two trackways (II and IV) and one footprint group (f). Three type specimens, one sauropod and two theropod, were determined during the course of the work. Since no dinosaur bones have been discovered in the Cenomanian rocks of Istria so far, these findings are outstandingly important in the analysis of the regional dinosaur fauna.
