Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. [1] This includes the study of body fossils, tracks ( ichnites ), burrows , cast-off parts, fossilised feces ( coprolites ), palynomorphs and chemical residues .
Basic Palaeontology is a basic textbook on the study of paleontology written by the palaeontologists Michael J. Benton and David A.T. Harper, and published by Prentice Hall in 1997. It was described in a 1998 review by palaeontologist Mark Purnell as being uniquely inclusive in its coverage of the subject, going into detail about the history of ...
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).
Hence, paleontology overlaps with geology (the study of rocks and rock formations) as well as with botany, biology, zoology and ecology – fields concerned with life forms and how they interact. The major subdivisions of paleontology include paleozoology (animals), paleobotany (plants) and micropaleontology ( microfossils ).
[10] [2] Additionally, paleohistological data can provide insights into paleoecological dynamics, such as population demographics , habitat preferences, and responses to environmental change. By reconstructing past environments and ecosystems , paleohistology helps scientists understand the long-term effects of climate change , mass extinctions ...
Paleozoology uses the methods and principles of paleobiology to understand fauna, both vertebrates and invertebrates. See also vertebrate and invertebrate paleontology, as well as paleoanthropology. Micropaleontology applies paleobiologic principles and methods to archaea, bacteria, protists and microscopic pollen/spores.
Fusulinid from the Plattsmouth Chert, Red Oak, Iowa ().Micropaleontology can be roughly divided into four areas of study on the basis of microfossil composition: (a) calcareous, as in coccoliths and foraminifera, (b) phosphatic, as in the study of some vertebrates, (c) siliceous, as in diatoms and radiolaria, or (d) organic, as in the pollen and spores studied in palynology.
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth , gradual and sudden, over this deep time .
