Palaeography is an essential skill for many historians, semioticians and philologists, as it addresses a suite of interrelated lines of inquiry.First, since the style of an alphabet, grapheme or sign system set within a register in each given dialect and language has evolved constantly, it is necessary to know how to decipher its individual substantive, occurrence make-up and constituency.
Palaeogeography yields information that is crucial to scientific understanding in a variety of contexts. For example, palaeogeographical analysis of sedimentary basins plays a key role in the field of petroleum geology, because ancient geomorphological environments of the Earth's surface are preserved in the stratigraphic record.
During the 17th century, Nicolas Steno was the first to observe and propose a number of basic principles of historical geology, including three key stratigraphic principles: the law of superposition, the principle of original horizontality, and the principle of lateral continuity.
The Paleozoic (/ ˌ p æ l i. ə ˈ z oʊ. ɪ k,-i. oʊ-, ˌ p eɪ-/ PAL-ee-ə-ZOH-ik, -ee-oh-, PAY-; [1] or Palaeozoic) Era is the first of three geological eras of the Phanerozoic Eon. . Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic (the last era of the Proterozoic Eon) and ends 251.9 Ma at the start of the Mesozoic Er
The names for archaeological periods vary enormously from region to region. This is a list of the main divisions by continent and region. Dating also varies considerably and those given are broad approximations across wide areas.
The simplest definition of "paleontology" is "the study of ancient life". [7] The field seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past".
The Paleoarchean (/ ˌ p eɪ l i oʊ. ɑːr ˈ k iː ə n, ˌ p æ l-/ PAY-lee-oh-ar-KEE-ən, PAL-), also spelled Palaeoarchaean (formerly known as the early Archean), is a geologic era within the Archean Eon.
Paleontography (from Ancient Greek παλαιός “old”, ὤν "being", γραφή "I write") is the formal description of fossil remains. [1] It is a subdiscipline of paleontology . The term has been in use in this sense for more than a hundred and fifty years, for example by the Palaeontographical Society .
