After the discovery of Early Jurassic sauropod tracks in northern Italy, Polish Liassic strata revealed a second comparably early record of sauropod footprints in Europe. In comparison with the Italian material, described tracks seem to be left by juvenile or small primitive sauropods, presumably 4.4 m and 5.5 m long.
Elusive tracks of stegosaurs have been long searched for by ichnologists, and various purported stegosaur imprints have recently been reported. A fragmentary trackway of a large, quadrupedal ornithischian dinosaur was found on an isolated slab of Oxfordian dolomite, on the northeastern slope of Holy Cross Mountains, Poland. The track is similar to large, blunt−toed Late Jurassic ichnites from North America. The footprints show a distinctive morphology, which fits the stegosaurian foot. The newly described ichnites from the Upper Jurassic of Poland provide the second ichnological evidence of the Late Jurassic dinosaurs in this country; numerous rich dinosaur footprint assemblages were previously known only from the Lower Jurassic outcrops.
