Create your own Jurrasic Park with the CollectA Stegosaurus Dinosaur Toy in green. The Stegosaurus was a huge, slow-moving, herbivorous dinosaur. It lived in the late Jurassic period, around 155-145 million years ago. Also, it had a powerful spiked tail that protected it from predators like the Allosaurus and Ceratosaurus. Stegosaurus grew up to nine metres in length and had surprisingly small heads - their brain was the size of a plum. Hand-painted and designed by experts, the dinosaur model is factually accurate and true to life. Suitable for ages three years and above. Size: 25.5 x 11cm.
