The Magic School Bus in the Time of the Dinosaurs is the sixth book in the original book series.


Ms. Frizzle is taking her class to a dinosaur dig to look for some Maiasaura nests. But as soon as they get there, the bus turns into a time machine and transports them back to prehistoric times--when dinosaurs roamed the Earth!


  • Although Carlos and Keesha were introduced in this book, this book was in production at the same time as the animated series that premiered the same year this book was published.
