Dinosaur soundscapes dominate this unusual take on the familiar reptilesBeat boxers and any readers willing to try a vocal cord workout will have a field day with this book, which features the sounds of the late Cretaceous. "Shhheka shekaaa…shkraaack." "Booouuush." "Kerrr kaaaw kaaaw kerrr." And that's just the warm-up. After we meet Terri the Triceratops, who's just broken out of her egg, we hear and then meet a crowd of her coevals, among them a "yowling" Saurolophus, several "prowling" Velociraptors, a pair of fighting Pachycephalosauruses, and a roaring Tyrannosaurus. In the one little pinch of plot, the unseen narrator, who describes events in a conversational tone, counsels Terri, face to face with the T. rex, to stay silent to avoid becoming lunch. But defiantly, Terri emits her own distinctive sound: "meep." And still louder, precipitating a hasty Tyrannosaurus retreat. A tiny Triceratops triumph! Striking illustrations depict the dinosaurs in dramatic-but not impossible-colors and patterns. The book takes place over the course of a single day, which readers can trace by noting the color and position of the glowing sun (and then moon). Terri's encounter with the T. rex coincides with a mauve and then indigo-dark night. Terri's discreet appearances on most pages provide another interactive element; little ones will enjoy finding her on each spread. Backmatter explains how we know what these animals sounded like.A boisterous invitation to roar, snort, and grunt like your favorite prehistoric creatures.
