3d. if the nyasasaurus parringtoni was found only in rock layer 2 and a fossil of an unknown plant was found only in rock layer 4, write a claim about what a paleontologist would know about the relative age of the nyasasaurus parringtoni and the unknown plant. use a complete sentence.
claim:

Explanation:

In geology, the principle of superposition states that in undisturbed sedimentary rock layers, the lower layers are older. Since the nyasasaurus parringtoni fossil is in layer 2 (lower) and the unknown plant fossil is in layer 4 (upper), we can use this principle.

Answer:

A paleontologist would know that the nyasasaurus parringtoni is older than the unknown plant.
