Flip-o-Storic

Like its predecessor, Flip-o-saurus, this innovative book, which opens calendar-style, displays portraits of several prehistoric animals cut into three lift-flaps, enabling readers to mix and match the animals' heads, torsos, and posteriors, creating new species. For example, the head of an icaronycteris (a bat named after Icarus), the legs of an ostrichlike gastornis, and the tail of a dorudon ("My tail looks like a dolphin's") blend to create an "icaro-tor-don." With hundreds of possible combinations and detailed descriptions of each physical component, readers will learn plenty, between giggles, about some unusual prehistoric animals. Ages 4%E2%80%93up.
