Cretaceous Period

My digital illustration of creatures in the Cretaceous Period, 145 - 66 Million Years Ago. In the air, left to right: Tapejara, Nyctosaurus, Quetzalcoatlus, Pteranodon. On the cliff, left to right: Spinosaurus, T Rex. On the ground, left to right: Qiupalong Henanensis, Alamosaurus herd, Alamosaurus, Ankylosaurus, Alamosaurus, Parasaurolophus, Sarcosuchus, Alamosaurus. Most people think the T Rex was part of the Jurassic Period because of the movies, but it was actually the big boy of the Cretaceous Period.
