1. Refer to Figure 9.13. Which photo(s) (AâI) best illustrate(s) the methods of fossilization or fossil evidence listed
below? (Photos/letters may be used more than once.)
Petrification: The small internal cavities and pores of an original organism that are filled with precipitated mineral
matter. Photo(s):
Cast: The space once occupied by a dissolved shell or other structure is subsequently filled with mineral matter.
Photo(s):
Carbonization: Preservation that occurs when fine sediment encases delicate plant or animal forms and leaves a
residue of carbon. Photo(s):
impression: A replica of an organism, such as a leaf, left in fine-grained sedimentary rock. Photo(s):
Amber: Hardened resin of ancient trees that preserved delicate organisms such as insects. Photo(s):
indirect evidence: Traces of prehistoric life but not the organism itself. Photo(s):
ACTIVITY 9.6
Types of Fossils
A. Crustacean (shrimp) B. Fossilized wood C. Fossil bee
D. Fossil brachiopods E. Dinosaur track F. Trilobite fossil
G. Fossil dung H. Fossil spider I. Fossil fish
