While this looks and feels like a book, A Brief History of Life on Earth is most certainly not what you expect from the cover. Within its pages, you do find a wealth of information; however, in an effort to help the reader conceptualize history on a grand scale, the book takes the form of an unfolding timeline of history the length of a triceratops (as it boasts on the cover). What struck me most about the book, besides the unique structure, is that it is easily digestible for children as well as beautifully illustrated. A nice surprise at the very end, when the human portion of the timeline comes into frame, is the diversity of people on the pages. While it's not your traditional book, I can see a great many uses for this text, both with my own children and in the classroom.
