The Spinosaurus animatronic was an animatronic puppet used in the film Jurassic Park III. It was used in many shots for Jurassic Park III, most prominently in the battle against the Tyrannosaurus rex animatronic. Due to the power of the puppet, the former managed to accidentally destroy the Tyrannosaurus animatronic puppet. It slapped the Tyrannosaur in the face, causing the latter’s neck to break, dismembering its head and releasing a hydraulic fluid. John Rosengrant said “that was a really sad ending to a long night of filming.
As of 2025, the location of the animatronic is unknown. But it's rumored that the animatronic's head was sold for 40-60k dollars at an auction in 2009.[1]
