虽然教室装饰成了恐龙之地，Frizzle女士通过考古挖掘激发灵感，渴望更真实的体验。于是魔法校车变成了时间机器，将学生们带回几百万年前，在那里他们去了解恐龙，还有恐龙的栖息地和饮食，还有慈母龙的筑巢地。

To celebrate its 20th anniversary, Scholastic is re-releasing the ten original Magic School Bus titles in paperback. With updated scientific information, the bestselling science series ever is back!
The classroom is decorated as Dinosaur Land, but Ms. Frizzle-inspired by an archeological dig-craves a more authentic experience. The Magic School Bus turns into a time machine and transports the class back millions of years to an adventure where they learn about dinosaurs, their habitats and diets, and even a Maiasaura nesting ground.
