Snails and relatives; many living species. On a larger scale, even between continents, fossil evidence can help in correlating rock layers. Arrange them from oldest to youngest with the oldest layer on the bottom and the youngest on top.

If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. The module is an integrated unit which addresses the following National Science Education Standards:

Sequence the remaining cards by using the same process. Primitive armored fish; extinct. The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence.
