Fossil

Fossil by Ewart, Claire. hardcover edition. ISBN: 9780802788900.

When dinosaurs thundered across the land, and enormous reptiles swam in the salty oceans, reptiles called pterosaurs ruled the ancient skies. Claire Ewart transports readers back to the age of the dinosaurs to take flight with a majestic pterosaur that once soared through North American skies more than ninety million years ago, following it from sunup to sunup. And when the pterosaur finally lives out its natural life, layers of Earth and layers of time work to transform this creature into a fossil-an amazing transformation that happens over millions of years.
