Answer: below new fossils
Step-by-step explanation:
Rocks are usually arranged in Layers of which the oldest are found in the bottom and the recent rock layers found on the top. This is in line with the Law of superposition which states that every rock layer is older than the one which lies above it, This law together with the Law of faunal / fossil succession helps us to understand the assemblage of fossils and how they succeed each other with time. From this, we can say that older fossils in a rock will lie farther below a rock layer leading to the oldest fossils occurring at the deepest part of the rock layers and the newest fossils appearing at the top of rock Layers.
We can therefore say that Older fossils appear in rock layers–below new fossils.
