This tyrannosaurus is a partial model of (Triceratops vs T-Rex Automata) and also an automaton that can function alone.
When you turn the lower handle, the Tyrannosaurus rex makes a roaring motion. Many joints in its body can rotate, including the jaw, forelimbs, legs, knees, and tail. The body also moves forward. Whenever this Tyrannosaurus roars, I think of the movie’s last scene of Jurassic Park in 1993.
