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 lovely, full-color 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 nonfiction picture book is an excellent choice to share during homeschooling, in particular for children ages 4 to 6. It's a fun way to learn to read and as a supplement for activity books for children.

Now rebranded with a new cover look, this book includes beautifully detailed illustrations and 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. Author/illustrator Aliki has penned four books listed as "exemplary" titles in the Common Core Standards and is a widely recognized name in nonfiction for children. Both text and artwork of this new edition were reviewed for accuracy by paleontologist Dr. Kathryn Hoppe and by Dr. William F. Simpson of the Field Museum.

This is a Level 2 Let's-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let's-Read-and-Find-Out Science is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
