Ancient Animals Plesiosaur

Más información sobre el libro

Ninety million years ago, giant dinosaurs roamed the earth, pterosaurs flew through the air, and giant reptiles and fish hunted in the oceans. The area that is now Kansas was covered by water and one of its inhabi-tants was the plesiosaur—a reptile with an extremely long neck and a huge body. This early reader about the ancient plesiosaur brings the prehistoric world of this ocean-dwelling animal to life, explain-ing how scientists think these reptiles lived, hunted, and became extinct. Back matter explores other reptiles both ancient and modern and provides additional print, visual, and web resources.
