An award-winning engaging kids' guide to the official US state fossils. Did you know that Illinois's state fossil is the weird-looking Tully Monster, which had eyes on a pair of stalks and an elephant-like trunk that ended in a toothed claw? Or that Idaho's state fossil is the stocky Hagerman horse, named for the town where its bones were found? Fossils can be found in every state, and this engaging guidebook brings these ancient organisms to life. Each state entry contains details about the state fossil; an illustration of what the vertebrate, invertebrate, or plant looked like; a photograph or drawing of the fossil; and a state map showing where it can be found. Potential fossil candidates are proposed for states that do not yet have official state fossils, along with instructions on how to get state fossils designated. An appendix lists museums and parks where these fossils can be studied first-hand. This book is a fun resource for fossil enthusiasts and future paleontologists of all ages.
