Transcript of Fossils
Do all dead organisms form fossils?
for half an hour
Conditions for fossil formation
Make a copy of the study guide. You can not copy each other, or share this document with each other.
The study guide is due before you take the test.
Fossils and Geologic Time
Types of Fossils
Mineral Replacement (Petrified)
Preserved remains or evidence of ancient
Fossils can only form under
Dead, but once living
Mostly made of hard parts
Protected quickly after it dies
Only in sedimentary rock
Will all rock types
Sedimentary, Igneous, Metamorphic
is the only rock type that
will preserve fossils
Who studies fossils?
Assemble the bones as a group
Draw what it would look like and work through the questions as a group.
What can dinosaur bones tell us about that particular dinosaur?
So what are some examples
that wouldn't be fossils
group will pick
type of preservation
1. What is it
2. How it happens
3. Draw out/pictures how it occurs
4. Environments favorable for this
5. Famous examples
6. What can this fossil tell us about the past
Fossils and Current Organisms Lab
How were the fossils similar and how were they different.
What is Relative Age Dating?
What is the Geologic Time Scale?
Time between the Precambrian and present
Paleozoic, Mesozoic, and Cenozoic
What eras are subdivided into
I can . . .
What evidence do you have?
How does this show evidence of evolution?
I can identify the basic types of fossils and explain how/where they formed.
I can identify similarities between fossils and current living organisms.
I can solve a variety of relative and absolute age dating problems.
I can explain the geologic time scale and provide important dates and information on that scale.
What do you already know about fossils?
What it ate
How long life has lived on Earth
Size and Shape
Habitat it lived in
Age of rocks and other geologic features compared to other rocks or features nearby
The processes that occur today are the same as in the past
The Law/Principle of Superposition
oldest on bottom, newest on top
A break or a gap in the fossil record
Record of the geological events and the evolution of life forms as shown in the fossil record.
