Dinosaur Footrprint (Grallator) - Massachusetts Chemical Formula: Na₈Al₆Si₆O₂₄ Cl₂Grallator is considered an ichnogenus. This means its class is determined by the footprints it left behind. Grallators include a variety of three toed prints created by theropod dinosaurs. These tracks have been found between the early Triassic Period (~250 million years ago) and the early Cretaceous Period (~130 million years ago). These specimens are found in the United States, Canada, Europe, Australia, Brazil, and China. Usually ranging between 4
