Articulated jaw really opens and closes! Cryolophosaurus is a dinosaur of the family Theropoda, that lived 183 to 189 million years ago during the Lower Jurassic Period. At 20 feet long and 1100 pounds, he was one of the greatest specimens of his time! It is distinguished by the presence of a crest bent backwards, whose function is still a mystery to scientists. The Papo Cryolophosaurus has been painstakingly hand-painted, with an extraordinary amount of detail being sculpted and painted. It features a hinged lower jaw, allowing the mouth to be open and closed. The Papo Cryolophosaurus measures approximately 5.5" L x 5" H. This figure is hand painted. Made of durable synthetic material.
