Dinosaur Footrprint (Grallator) - Massachusetts Chemical Formula: Cu3(CO3)2(OH)2Grallator 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).
