Lockatong Formation (PA) - All footprints here are from the late Triassic Period (220 mya) from the Lockatong Formation. The formation consists of dark gray and reddish to brownish sandstones and shale which were deposited during the formation of the Newark rift basin. Typical ichnotaxon list: Apatopus sp. (phytosaur), Atreipus sp. (ornithischian dinosaur), Brachychirotherium (rauisuchian crurotarsan), Grallator parallelus (small theropod dinosaur), Gwyneddichnium sp. (tanystropheid), Rhynchosauroides sp. (lepidosauromorphs), and others.
