1 Daily Warm-Up Exercises Day 37 What are index fossils? Index fossils are the remains or traces of organisms that lived for only a short time, but in many places around the world. Why are index fossils useful to geologists? When geologists find an index fossil in a rock layer, they know it is about the same age as all other rock layers that contain the same index fossil.
2 Use Index Fossils (Part 1, steps 10-12) Investigation 7 Fossils and Time
3 Index Fossil Correlations Turn to page 61 and cut out the profiles of Bryce Canyon and Zion National Park. Color all the same fossils the same color. Ex: color all the Wingatea pink. Place the two profiles on page 59 and attach them so the index fossils are aligned correctly. (Line up the layers with the same fossils.)
4 Kaibab and Z1 have the same index fossils Same at Grand Canyon & Zion
5 Z7 and B5 have the same index fossils Z2 and B1 also have the same index fossils Same at Zion & Bryce
Wrap up Turn to page 63 and complete the index-fossil correlation questions. You will turn in yesterdays Index Fossil ws, your correlated paper that you glued the layers on and pg. 63 all at the same time. Turn in to me in this order: On top: Index Fossils and ID ws Next: The 3 canyons lined up Last page: Ws 63, Index Fossil Questions 14
