Fossils Older Rock Layers. As scientists collected fossils from different rock layers and formations, they. the principle of superposition states that within a sequence of rock layers, the oldest layer is at the bottom, and the. In other words, you can use superposition to tell you that one rock layer is older than another. Did trilobites live before or after the dinosaurs? the layers of the rocks are the pages in our history book. layers of rock are deposited horizontally at the bottom of a lake (principle of original horizontality). But determining the absolute age of a substance (its age in years) is a much greater challenge. as we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects. in older rocks, fossils are less similar to modern organisms. Outline how natural selection takes place as a mechanism of evolution. Relative age dating has to do. define a fossil and describe types of fossil preservation. did rock layer a form before or after rock layer b?
