The Devět Křížů quarry is a well-known locality because of the discovery of a tridactyl footprint, which was first described in 1998 and attributed to a theropod dinosaur. This dinosaur footprint was found in kaolinitic quartz sandstones in the upper part of the Bohdašín Formation (Krkonoše-Piedmont Basin), located in the northern part of the Vindelic land. The age of the formation was originally considered Early Triassic based on sedimentological studies. However, such dating is inconsistent with the presence of dinosaur footprints, as the Early Triassic period does not support their occurrence. To date, dozens of invertebrate and vertebrate tracks have been documented in the quarry, including several tridactyl footprints assigned to Anomoepus isp. and Kayentapus isp., as well as numerous trackways attributed to Dicynodontipus isp., all of which are identified here for the first time. The first two mentioned ichnotaxa are primarily found in the Lower Jurassic and less frequently in the Upper Triassic deposits. The trackmakers of the Anomoepus tracks are considered to be early ornithischians, whereas the Kayentapus tracks were probably made by smaller theropods. Despite this, the Early Jurassic age of the locality seems unlikely, given the presence of cynodont therapsid tracks assigned to the ichnotaxon Dicynodontipus, which has never been found in Jurassic deposits. Therefore, based on tetrapod footprint biostratigraphy, we consider the upper part of the Bohdašín Formation to be the Late Triassic in age. The Late Triassic was a crucial epoch for the evolutionary radiation of various tetrapod groups, including, among others, dinosaurs, mammaliaforms, crocodyliforms, lissamphibians, and lepidosaurs. However, the ichnological record of some tetrapod groups from this epoch remains relatively limited compared to the body fossils; notably, therapsid tracks are only rarely preserved. The ichnofossils from the Bohdašín Formation thus provide valuable new insights into the palaeobiodiversity and palaeogeographic distribution of terrestrial tetrapods during the Late Triassic.
