What is a fossil?
A fossil is the remains or evidence of any
creature or plant that once lived on the
Earth.
World's Largest Coprolite (Dino Doo) Found.
Alberta, Canada - Canada has one more notable to hang on it's wall, the biggest
tyrannosaurid turd in the world. And it is very well preserved at that. Scientists have
been going googoo over how incredibly well preserved the 6.7 inch wide and 25.2 inch
long dino dropping is. They've been able to identify dino muscle tissue and bone.
Fossil Activity
• Objective: To identify the different types of fossils,
how fossils form, where fossils are found, and what
fossils tells us by conducting in depth research.
• 1. You will work individually to research fossils.
• To earn credit for this assignment you need to write 1
correct fact in the categories about fossils on the
board. Initial your facts.
• 3. While you are researching and recording your
findings on the board complete the fossil chart.
• 4. You will have about 15 minutes to do this.
Welcome to Science 1/12
• On your paper, create a simple time line
that shows the 5 most important events in
your life.
• Today’s Schedule
• 1. Question of the Day
• 2. Conclude Discussion on Fossils
• 3. Begin the Geologic Time Scale Project
Question of the Day
Rocks and Fossils
• What happens immediately
when something dies?
• Flesh & muscle decay leaving hard parts
behind. Nasty By Nature: Maggot Eating Machines : Video : Discovery Channel
• Sometimes these hard parts
are buried with sediment
and turn to rock/fossils
How Do Fossils Form?
• Fossils can form in amber/tree sap.
How Do Fossils Form?
• Mummification- bodies that die in extremely
dry or cold environments can dry out or freeze
before they can decay.
• Many mummies are perfectly preserved.
How Do Fossils Form?
• Fossils in tar- 1,000s of years ago there were
pits of thick, sticky tar that trapped animals and
preserved there remains
• HowStuffWorks Videos "Prehistoric: Death by Tar Pit"
How Do Fossils Form?
• Trace Fossils- any naturally preserved
evidence of an animal’s activity
• Tracks, burrows, and coprolites (dino-doo)
• Greatest Discoveries: Laetoli Footprints : Video
: Science Channel
What do fossils tell us?
•
•
•
•
•
Reveal changes in environments
Coral fossils have been found in Iowa/
Iowa was once underwater
Fish fossils have been found on mountains.
Mountains were once the bottom of oceans
What do fossils tell us?
• Reveal changes in life
• Index fossils- reveal the
age of rocks
Geologic Time Scale
Dailymotion - Are fossils proof for Darwin's theory of evolution?, a video from firstsciencetv. darwin, evolution, intelligent-design, creation, atheism
Geologic Time
The Geologic Time Scale
is a timeline of Earth’s
4.6 billion year old history
made using evidence
from fossils.
It shows how life has
changed on Earth.
Making a Geologic Time Scale Project
• Objective: Reconstruct the Geologic Time Scale
into a Geologic Timeline by placing events and
fossils in the proper locations.
• 1. Project Manager, Constructer, 2 Researchers
• 2. Roll of paper, meter stick, scissors, glue
• 3. You will need to work together to complete
this project.
• 4. The tentative due date is by the end of class
tomorrow.
• 5. Do your best. Be neat. Ask Questions
