A gigantic theropod footprint was discovered in the Hettangian alluvial plain deposits of the Holy Cross Mountains, central Poland. This discovery, along with a previous find in Arizona, provides ichnological evidence of a global occurrence of gigantic predatory dinosaurs in the Early Jurassic. The geographic and stratigraphic distribution of such gigantic theropods in Jurassic times was wider than generally believed. However, it seems justified to assume that very large theropods were less common in the Early Jurassic communities than they became in the Late Jurassic.
