All of the fossils represented would be found in sedimentary rocks of marine origin. If the letters "T" and "C" represent fossils in the oldest rock layer, they are the oldest fossils, or the first fossils formed in the past for this sequence of rock layers. In a "normal" horizontal sequence of rocks, the oldest rock layers will be on the bottom with successively younger rocks on top. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed. For example, most limestones represent marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or a riverbed.

A Relative Dating Activity is a hands on exercise which introduces students to the concepts of sequencing and using fossils to establish relative dates for rock strata. In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards. In the second part of the activity, students progress to dating rock layers by sequencing fossils found in the different strata. Using the results of these activities, teachers can then lead students in a discussion of the Law of Superposition and the identification and value of index fossils.
