Explanation:

In geology (a subfield of Natural Science, specifically related to Earth Sciences which can be considered under Geography or its own subfield), the layers of rock (sedimentary or igneous) that contain certain fossils and are used for relative dating and understanding the geological time scale are called "beds" or more specifically "strata" (the singular is "stratum"). The term "strata" (or "beds") refers to the distinct layers of rock that are formed over time, and fossils within these layers help in studying the history of life and the Earth's formation.

Answer:

strata (or beds, but strata is the more specific term for rock layers with fossils in geological context)
