Paleontology (/ ˌ p eɪ l i ɒ n ˈ t ɒ l ə dʒ i, ˌ p æ l i-,-ən-/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -ən-), also spelled palaeontology [a] or palæontology, is the scientific study of life that existed prior to the start of the Holocene epoch (roughly 11,700 years before present).
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them. [1] The primary objective of biostratigraphy is correlation , demonstrating that a particular horizon in one geological section represents the same period of time as another ...
It is the process where distinct strata between defined stratigraphic horizons are assigned to represent a relative interval of geologic time. A chronostratigraphic unit is a body of rock, layered or unlayered, that is defined between specified stratigraphic horizons which represent specified intervals of geologic time. They include all rocks ...

Stratigraphy is a branch of geology concerned with the study of rock layers and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks . Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy ...
Paleontological levels of first appearance of primorid mammals in South Africa and their ichnology. Establishment of detailed stratigraphic zones in the Lesotho Stormberg (South Africa) (Upper to Jurassic Triassic) [The paleontological levels of the primordial appearance of primordial mammals in southern Africa and their ichnology.
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
A paleontological or fossiliferous site is a locality in which a significant quantity of fossils is naturally preserved in the rocks. The extent of the site is determined, in some cases, by the spatial distribution of the concentration of fossils and in others by practical issues of sampling or excavation.
