I can recall the steps involved in sedimentation and fossilization. #dok1
I can explain how sedimentation affects the formation of fossils. #dok2
I can describe how fossilization influences the degree of completeness of the fossil record. #dok2
I can explain how speciation can affect the representation of organisms in the fossil record. #dok2
I can analyze how different rates or occurrences of sedimentation, fossilization, and speciation affect what is preserved in the fossil record. #dok3
I can evaluate how gaps and biases in the fossil record impact our understanding of Earth's history. #dok3

The processes of sedimentation, fossilization, and speciation directly influence how complete or incomplete the fossil record appears.
Understanding limitations and influences on the fossil record helps us interpret Earth's biological and geological past.

How does sedimentation impact what gets preserved in the fossil record?
In what ways does the process of fossilization affect the completeness of our fossil evidence?
How does speciation contribute to gaps or patterns within the fossil record?
What factors limit or enhance the degree of completeness of the fossil record?
Why is it important to recognize the factors influencing what we find in the fossil record?
