A layer of stratigraphy in one location overwhelmingly represents one species, while the same species is discovered in a similar stratigraphic layer fifty miles away. What method is used to provide an estimate of age for this layer and this species?
A) biostratigraphy
B) dendrochronology
C) Steno's law of superposition
D) carbon 14

Biostratigraphy uses the presence and absence of specific fossil species to correlate and date rock layers across different locations. This method is commonly used to estimate the age of sedimentary rocks and the fossils they contain. Dendrochronology is the study of tree rings and is not applicable to the scenario described. Steno's law of superposition is a basic principle of stratigraphy that states that new layers of sediment are deposited on top of older layers, but it does not provide a specific method for dating those layers. Carbon 14 dating is a method used to date organic material up to 50,000 years old, but it is not applicable to the scenario described as it requires organic material to be present.
