Two layers of rock contain fossils of the same kinds of trilobites; however, one rock layer is a shale and the other is a limestone. Can these two layers be used for correlation? Correlating Shale and Limestone Layers Containing the Same Trilobite Fossils

The Same Trilobite Fossils are found in Correlating Limestone and Shale Layers
Geology uses correlation to find the age of rock stratigraphy and determine their relative stratigraphic relationships. The process of correlation involves comparing each layer’s fossils and trying to determine similarities. This case shows that fossils from two different rock layers, a limestone and a shale have been discovered to be the same kinds of trilobites. These rock layers can be combined to form correlation. However, there are a few things you need to know. The most important of these is that the rock layers must be contemporaneous (Lüning, 2019). This means that they should have been laid in the same place at the same moment. The two layers of rock can then be used to understand the relationship between the layers and their age. Also, fossils of the same species are required, because variation in trilobite species may indicate different environments, or ages (Chen and al., 2015). The same trilobite fossils are found in limestone and shale layers.
