Otozoum ("giant animal") tracks are Triassic-era, fossilized footprints and other markings in sandstones. They were made by heavy, bipedal animals (probably dinosaurs) with a short stride that walked on four toes directed forward. Otozoum tracks were discovered by American paleontologist Edward Hitchcock, who described Otozoum as the "most extraordinary track yet brought to light in this valley [the Connecticut River] representing a bipedal animal... distinguished from all others... in the sandstone of New England".
