In this example, the study of layered rocks and the fossils they contain is called biostratigraphy and utilizes amassed geobiology and geologic timeline.

Schiebout's research focuses on paleoecology and vertebrate paleontology, particularly the biostratigraphy and paleogeography of southern North America in the Cenozoic era.
33.
Stages are primarily defined by a consistent set of fossils ( biostratigraphy ) or a consistent magnetic polarity ( see paleomagnetism ) in the rock.
34.
This has allowed for a tight correlation of the age of the Gault with other geological units in Europe, under the science of biostratigraphy.
35.
The top of the Danian stage ( the base of the Selandian ) is close to the boundary between biozones NP4 and NP5 from marine biostratigraphy.
36.
His work largely dealt with the comparative anatomy of fossil plants, comparative morphological investigations of living and fossil plants, and studies involving Carboniferous biostratigraphy.
37.
Recent studies of the biostratigraphy and magnetostratigraphy of the area have shown that the Wi�ry site is Early Spathian ( Early to Late Olenekian ) in age.
38.
Alvarez and his colleagues were able to date the reversals for an interval of more than 100 million years of the Earth's history by using Foraminifera biostratigraphy.
39.
Geochronology is different in application from biostratigraphy, which is the science of assigning sedimentary rocks to a known geological period via describing, cataloguing and comparing fossil floral and faunal assemblages.

In 1973, Kitching was awarded a PhD degree by the University of the Witwatersrand for his thirty years of intensive work on the biostratigraphy of the Karoo Supergroup in South Africa.
