This lifelike Protosuchus animatronic model is 3.3 feet (1 meter) long. We painted dark purple markings, Instal motors make it can wave its tail and swing its head. Protosuchus is a small terrestrial carnivore that lived in North America in the early Jurassic period. It moved swiftly, walking trembling in the shadows of the early carnivorous dinosaurs like Herrerasaurus and Coelophysis. Protosuchus was living in the water, hunting in the water, but also crawling to the shore to bask in the sun.
