Meaning and Definition
The branch of stratigraphy that uses fossil organisms to date and correlate rock layers.
The study and application of the distribution of fossils in sedimentary rock layers to establish their relative ages and the chronological order of geological events.

FAQ
Frequently Asked Questions
No. Biostratigraphy provides relative ages (older/younger) by comparing fossil assemblages. Radiometric dating provides absolute numerical ages by measuring radioactive decay.
Primarily stratigraphers, paleontologists, and petroleum geologists use it to date sedimentary rocks and correlate geological sections across different locations.
Generally, no. It requires sedimentary rocks that contain fossils. Igneous rocks are dated using radiometric methods.
It is a body of rock defined by its fossil content, representing a specific interval of geological time. It is the fundamental unit of biostratigraphy.
The branch of stratigraphy that uses fossil organisms to date and correlate rock layers.
Biostratigraphy is usually technical/scientific in register.
Biostratigraphy: in British English it is pronounced /ˌbaɪ.əʊ.strəˈtɪɡ.rə.fi/, and in American English it is pronounced /ˌbaɪ.oʊ.strəˈtɪɡ.rə.fi/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think: BIO (life/fossils) + STRATI (layers) + GRAPHY (writing/recording) = 'recording the layers using fossils'.
Conceptual Metaphor
Fossils as pages in a calendar buried within the rock book.
