Exercise 4.2: Interpreting Fossils
Watch this video to learn about different methods paleontologists use for dating fossils.
1. What is stratigraphy?
2. Using your knowledge of plate tectonics and mountain building, what do you think the main problem is with dating fossils using stratigraphy?
3. What is “radio carbon” or “radio isotope” dating? What two elements are discussed in the video?
4. What is an “index fossil”? How are they useful to paleontologists?
