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).
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 ...
Although best known as the discoverer of the mid-Cambrian Burgess shale animal fossils, in 1883 this American curator found the "first Precambrian fossil cells known to science" – a stromatolite reef then known as Cryptozoon algae. In 1899 he discovered the first acritarch fossil cells, a Precambrian algal phytoplankton he named Chuaria.
Classic paleoecology uses data from fossils and subfossils to reconstruct the ecosystems of the past. It involves the study of fossil organisms and their associated remains (such as shells, teeth, pollen, and seeds), which can help in the interpretation of their life cycle, living interactions, natural environment, communities, and manner of death and burial.
A geologist is a contributor to the science of geology.Geologists are also known as earth scientists or geoscientists.. The following is a list of notable geologists. Many have received such awards as the Penrose Medal or the Wollaston Medal, or have been inducted into the National Academy of Sciences or the Royal Society.
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.
Palaeontology: the classification and taxonomy of fossils within the geological record and the construction of a palaeontological history of the Earth. Pedology: the study of soil, soil formation, and regolith formation. Petroleum geology: the study of sedimentary basins applied to the search for hydrocarbons (oil exploration).
To analyze human remains of the past, different techniques are used depending on the type of remains that are found. For example, "the approach to palaeopathological samples depends on the nature of the sample itself (e.g. bone, soft tissue or hair), its size (from minimal fragments to full bodies), the degree of preservation and, very importantly, the manipulation allowed (from intact sample ...
