All of the fossils represented would be found in sedimentary rocks of marine origin. This principle allows sedimentary layers to be viewed as a form of vertical time line, a partial or complete record of the time elapsed from deposition of the lowest layer to deposition of the highest bed. The following is a list of fossils in the John Hanley Fossil Teaching Set that may be useful in this activity. While digging the Somerset Coal Canal in southwest England, he found that fossils were always in the same order in the rock layers. Craters are very useful in relative dating; as a general rule, the younger a planetary surface is, the fewer craters it has. Each card represents a particular rock layer with a collection of fossils that are found in that particular rock stratum. Due to that discovery, Smith was able to recognize the order that the rocks were formed. In geology, when an igneous intrusion cuts across a formation of sedimentary rock , it can be determined that the igneous intrusion is younger than the sedimentary rock. Observation of modern marine and non-marine sediments in a wide variety of environments supports this generalization although cross-bedding is inclined, the overall orientation of cross-bedded units is horizontal. General principle Archaeologists, geologists, and other scientists make use of this principle when dating sediments or layers relative to one another:

    When you finish, you should have a vertical stack of cards with the top card representing the youngest fossils of this rock sequence and the "TC" card at the bottom of the stack representing the oldest fossils. Drawbacks of relative dating methods Relative methods do not always reflect the true sequence of events in time.

    Once an organism disappears from the sequence it cannot reappear later. Sediments are usually laid down in horizontal beds.
