A budding "Expert-osaurus" shares some information on all things dinosaur.The young narrator loves everything about dinos: knowing their names, reading about them, learning facts (some could fly; some were herbivores, some carnivores), attending dino-themed parties, visiting a cool dinosaur museum, digging up fossils with a paleontologist, making a volcano, and practicing dinosaur roars. But the bonus attraction is knowing that dinosaurs are extinct, "so they'll never catch me!" McClurkan's appealing cartoon illustrations mix pastels with bright Day-Glo hues, using little or no outlining and full but uncluttered compositions. As in the publisher's other 10 Things titles, this book has a counting element (the child lists favorite things about dinosaurs, in numerical order), but, apart from the cover, no numerals can be found, only number words. And while three bluebirds happen to be on the page for Number 3, no counting elements are hidden in the pictures-a missed opportunity. Still, it's an exuberant romp that dino fans will find relatable; they'll especially love the dino facts. The narrator is light-skinned with short brown hair. Mom, Dad, and a sister are also light-skinned, while the protagonist's brother is brown-skinned. People throughout are racially diverse, and a character who uses a wheelchair can be seen at the museum.Sure to please young dinophiles. (pronunciation help) (Picture book. 3-7)
