This book highlights a newly discovered T. rex relative in China with a coat of downy feathers! This one-ton predator is the largest known animal to ever have walked the Earth. This discovery was made public in April 2012, and is a timely addition that sets this book apart from other dinosaur titles.

We meet 19 kinds of tyrannosaurs-including seven new species discovered in the last two years-that came before T. rex. The names are strange, like Bistahieversor and Zhuchengtyrannus. The creatures were strange, too, and many of the newly discovered ones caught scientists by surprise. Filled with engaging, lifelike illustrations by Xing Lida, Tracking Tyrannosaurs explains to kids how T. rex, the most famous, ferocious dinosaur of all-time was only one of many tyrannosaurs that lived on Earth for over 100 million years!
