Sediments / Fossilization
The Geology Book
- Sand is made primarily of what mineral?
- Write a paragraph describing how sedimentary rocks are formed.
- What conditions are required to form a fossil?
- Name four different types of fossils.
- In you own words, write a description of how dinosaur fossils are formed.
NOTE: This week’s activities reinforce the fact that fossils and petrified wood can be made over a short period of time.
- Make a “fossil” using plaster of paris. Mix the plaster of paris and pour it onto a paper plate. Gather different objects (leaves, toy dinosaurs, etc.), press each into the plaster of paris, and then lift the object off. Include a print of your hand or foot. Let dry. Paint, when dry, if desired.
- This is week 3 of the experiment started in Lesson 3. Has your mound decreased any? What caused this decrease?
- See page 37.
- That the organism be buried rapidly, protected from scavengers and from decomposition by bacteria and chemicals
- Hard parts are preserved; replacement by other minerals; cast or mold are all that remains; petrification; cabonization; preservation of soft parts; frozen animals; animal tracks and worm burrows; coprolites; gastroliths
- See page 41.
