Stegosaurus, the walking fortress of the late Jurassic period, is the newest Ugears dinosaur automaton, joining the Tyrannosaurus Rex and Triceratops in the Ugears dino collection. With its double row of bony protective plates running down its spine and its spiked mace-like tail, Stegosaurus is one of the most iconic dinosaurs in the fossil record. Unleash your inner paleontologist as you bring this giant back to life!

The Stegosaurus by Ugears is a spring-driven, four-legged DIY wooden dino automaton, able to walk up to one meter on a single winding. The winding key is found in the dino's belly, with paired winding slots located on each side. The bony plate above the dinosaur's shoulder functions as a "Start/Stop" switch. Push the plate back before giving up to ten half-turns of the key, then set the Stegosaurus on a flat surface, slide the shoulder plate forward, and watch your living fossil lumber off in search of its next meal! An eccentric gear sets the tail swaying in synchronous motion with the legs, helping the dinosaur walk in life-like fashion.

The overlapping plates on the Ugears Stegosaurus are arranged in a double row, as per the arrived-at consensus among paleontologists today. There is still a lively debate about their principal function, whether for defense, thermoregulation, or courtship display, but we think having one of these plates serve as the dinosaur's Start/Stop switch is a fun innovation!
