Abstract

Inside NP Brijuni there are 4 localities containing fossil dinosaur footprints, which make this area one of the richest of the former Adriatic- Dinaridic Carbonate Platform. A new locality rich with dinosaur tracks has recently been discovered in the Brijuni archipelago. The locality is situated on the islet of Vrsar, west of the Veli Brijun island. The footprint bearing layer contains 65 footprints and 11 trackways, some of them closely spaced, which could indicate gregarious behaviour. All footprints show distinct tridactyl morphology with long and slender digit impressions, that are typical for theropod dinosaurs. Standard ichnological measurements were made on all the footprints. Estimated dinosaur speeds range from 5.4 to 7.5 km/h, while the size of individuals ranges from 3 - 4 m. Besides paleoichnological measurements, sedimentological analisys was made by studying microscopical samples, which showed that the environment was likely a tidal flat (intertidal/shallowsubtidal). The microfossil assemblage in the studied samples hints at a Barremian age of the trackbearing sediments.
