One of the great marine reptiles of the Cretaceous Period, the Mosasaurus, was a huge aquatic lizard approximately 50 feet long. CollectA Deluxe 1:40 scale version features a movable jaw which shows off the creature’s large conical teeth. The Mosasaurus was a carnivore that often fed on fish, sharks and even other Mosasaurs! This replica has been designed with a nick in the top of its fin to look as if it’s been bitten by a fellow Mosasaur. This hand-painted dinosaur toy looks lifelike and realistic. Designed by experts, CollectA dinosaur models are factually accurate and true to life.
