Strata Order Game

Show that you know the order of the seven most important index fossils. Select fossils under "Drag" and drop them in the "Drop" zones, youngest to oldest. Then check your answer.

Need a Little Help?

If you don't have the index fossil order memorized, you can use the sample strata columns below and a little logic to figure out the order. Hint: Fossils from some eras get worn away before new layers are deposited. This is why there is no place in the world with a complete sequence of fossils.
