Jane Yolen and Mark Teague's phenomenally best-selling dinosaurs are back, and this time they're going to school! What would you do if a very large ceratosaurus stomped into your classroom? And what if the student sitting next to you was a gigantic silvisaurus -- who decided to jump on top of his desk? Come along for a very unusual day where dinosaur show-and-tell, story time and playtime antics will make even the best-behaved dinosaurs laugh out loud. School has never been so much fun!
