Read and find out about fossils in this colorfully illustrated nonfiction picture book.

What is a fossil? Sometimes it''s the imprint of an ancient leaf in a rock. Or it could be the skeleton of a dinosaur that has turned to stone. With clear prose and beautifully detailed illustrations, award-winning author and illustrator Aliki describes the different ways fossils are formed and what they tell us about life on Earth long ago.

This is a clear and appealing science book for early elementary age kids, both at home and in the classroom. It includes a find out more section with a glossary and activity guide so kids can create their own fossils for someone to find a million years from now.
