Anticheiropus hamatus

Anticheiropus hamatus

†Anticheiropus hamatus is a dinosaur ichnotaxon (fossil manus track) from the Early Jurassic of the eastern United States. These hand-only impressions are thought to record the resting or foraging posture of a quadrupedal dinosaur. Found in Newark Supergroup deposits, Anticheiropus tracks complement bipedal trackways and help reconstruct locomotor behaviour in Early Jurassic dinosaurs.

Time Period

Jurassic Early Mesozoic Era

Anticheiropus hamatus lived during the Jurassic Early period of the Mesozoic Era, approximately 201.4 to 174.7 million years ago.

After the Triassic-Jurassic extinction, dinosaurs rapidly diversified and became the dominant land vertebrates. Early sauropods and theropods began to evolve larger body sizes.
