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 ...
e. Paleontology (/ ˌpeɪliɒnˈtɒlədʒi, ˌpæli -, - 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). [citation needed] It includes the study of fossils to classify ...

The timeline of the evolutionary history of liferepresents the current scientific theoryoutlining the major events during the development of lifeon planet Earth. Dates in this article are consensus estimates based on scientific evidence, mainly fossils. In biology, evolutionis any change across successive generations in the heritable ...

Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
A noteworthy feature of Paleozoic life is the sudden appearance of nearly all of the invertebrate animal phyla in great abundance at the beginning of the Cambrian. The first vertebrates appeared in the form of primitive fish, which greatly diversified in the Silurian and Devonian Periods. The first animals to venture onto dry land were the ...
Fossil wood is wood that is preserved in the fossil record. Wood is usually the part of a plant that is best preserved (and most easily found). Fossil wood may or may not be petrified. The fossil wood may be the only part of the plant that has been preserved; [99] therefore such wood may get a special kind of botanical name.
