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.

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.


化石是什麼呢？它有時是岩石裡古代樹葉的痕跡，也可能是恐龍骨頭變成的石頭！得獎作者暨插圖家艾麗奇運用簡單的文字與精美全彩插圖，述說化石形成的不同原因，還有從化石裡我們能一窺地球早期生命的面貌。

本書改版搭配新封面，內含精美細膩的插圖，也收錄「發現更多」單元，附上單字和引導活動的指南，讓孩子動手做出距今百萬年前的化石。

艾麗奇筆下的四本書列為共同核心標準中的「典範」，也是童書中知名的非小說類作品。新版書中內文和插圖都經過古生物學家 Kathryn Hoppe 博士與菲爾德自然史博物館 William F. Simpson 博士審核，確保正確無誤。

本書為此系列叢書的第二級讀本，對於低年級的小學生來說，書中的概念更有挑戰性。本書符合共同核心標準、新世代科學標準和 STEM 教育（科學、技術、工程、數學）標準，更榮獲美國科學促進會獎∕斯巴魯優秀科學系列科學書籍和電影獎（Subaru Science Books & Films Prize for Outstanding Science Series）。
