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.
