Meet Megatooth -- the giant prehistoric shark that was even bigger than T-rex!

Ten million years ago, giant beasts walked the earth. But the biggest one of all did not walk -- it swam. It was large enough to eat whales. It was more enormous than the biggest dinosaur, Tyrannosaurus rex. It was Megalodon -- or Megatooth -- the giant shark, and it ruled the seas. Great White sharks may be huge, but their ancient ancestors were even bigger and more powerful. Scientists aren't sure how big Megalodons really were, since the only things they left behind were enormous teeth. But teeth can tell us a lot. Filled with fascinating facts and gorgeous, highly detailed illustrations, this book will thrill dinosaur and shark fans alike.

Patrick O'Brien has been fascinated with prehistoric animals since he was a child. This interest led him to write and illustrate both Megatooth! and Gigantic! How Big Were the Dinosaurs? He lives with his wife in Baltimore, Maryland.
