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!
