Which of the following best describes what we mean when we talk about the fossil record? (Mark the best answer)
Leaf imprints found in the hardened mud
The history of fossils in the last 400,000 years
A fossil found in rock
All the fossils that have been discovered
Please Mark all that apply which explain why the fossil record is considered incomplete.
Not all organisms become fossils
Some organisms have not been extinct long enough
There were times when fossils didn't form
There are still fossils that haven't been found
Some organisms are too small to make fossils
These images represent the limbs of extinct organisms found in the fossil record: Write the letters of the fossil limbs in order from oldest (most ancient) to youngest (most recent).

Why do we find more fossils of organisms such as snails and vertebrates than organisms such as jellyfish?
Snails have more soft parts
Vertebrates and snails have hard parts
Jellyfish have soft parts
Jellyfish have more hard parts than snails and vertebrates
Fossils were discovered in four different layers of rock, A,B,C, and D. Please check the ones that are true. Check all that apply.
Fossils found in layer A are most likely older than fossils found in layer B
The age of a fossil is the same age as the rock it is found in
Organisms with shells appeared before tetrapods
Fish and organisms with shells lived at the same time
According to the principle of superposition, layer D represents the oldest rock
Which of the following provides evidence that fossils of limb structures from ancient and modern tetrapods are related?
We know that ancient and modern tetrapods are related because they shared similar structures, such as a long bone
They are not related
Their names are closely related so we just say that they are related
The soft parts of ancient organisms are the same as that found in modern organisms
What ancient organism was the transitional organism between Eusthenopteron and the Acanthostega?
Pederpes
Tiktaalik
T-Rex
Lungfish
