Oldest Known Evidence of Dinosaurs

Caption

The 250 million year old footprints of Prorotodactylus isp. from the Early Olenekian of Stryczowice, Poland show reduced digits I and V and parallel three middle digits, traits of the dinosaur-lineage. The gait, though, was quadrapedal. These are the oldest known fossils of the dinosaur lineage.
