Like the other 3rd Series dinosaurs, the Pachyrhinosaurus is one of the rarest pieces in the entire line, having only a limited production run, predominately in the western United States and Europe. The Pachyrhinosaurus had the exact same body mold as the Triceratops and Torosaurus but with a different head sculpt and color scheme. The Pachyrhinosaurus also had motorized walking action and its head swayed from side to side as it walked. Despite its minimal equipment, the Pachyrhinosaurus is a highly sought after toy.
