Teachers, save “The Geologic Time Scale - Mesozoic Era A…” to assign it to your class.

Use the draw and label tool to add significant events on Earth during the three periods of the Mesozoic Era: they are the Triassic, Jurassic and Cretaceous periods. You can find significant events during these times on the attached PDF Pathway through Earth's life. Make sure you add them in the correct order by checking the timeline below each period.
