Lockatong Formation (NJ & NY) - 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.

1-3) On the other side of the slab (the one above with the two sloppy print casts) has what I believe might be the manus of a Brachychirotherium. The first photo is the full picture of the back of the slab, the print is on the top right of the first photo (photo was rotated to enhance the print). Inlargements of the same print (second photo) and an attempt to sketch it (third photo).

1-2) Two well defined prints on one slab probably from the dinosaur Coelophysis. Found in Nyack, NY. Special thanks to Jen for the photos.

1&2) A sloppy print, both halves, possibly a Grallator or Coelophysis. 3) Two prints in opposite directions. The one on the top appears to have four toes, the one on the right side could be a Grallator or Coelophysis, and the round bump in the center could be a manus print. 4) Sloppy prints. Photos 1-4 are the only ones from NY.

1) Two sloppy prints (casts), both might have three toes but it's only a guess.
