Students measure and sketch physical characteristics of 15 fossilized horse teeth. Each student group creates a graph that summarizes the trend between age of the fossil and length of the tooth. Plant information cards summarizing the flora of each epoch and guided analysis questions allow students to develop an explanation for the change in horse teeth in response to plant evolution due to a changing climate.
