Universities use 0–100 point grade scaling similar to the United States grading. 71 is required to pass, or roughly the equivalent of a C. Schools use the 1–5 point system, meaning if a student has a 4.5 that is the equivalent of an A− or somewhere around the 95-point range.
Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
The full taxobox guide is located at Wikipedia:Automated taxobox system. Detailed taxonomic information, including notes on how taxa are defined and how they vary between different systems, belongs in the article proper.
Below is the grading system found to be most commonly used in United States public high schools, according to the 2009 High School Transcript Study. [2] This is the most used grading system; however, there are some schools that use an edited version of the college system, which means 89.5 or above becomes an A average, 79.5 becomes a B, and so on.
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.
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 ...
Biostratigraphy, a branch of paleontology and paleobotany, involves fossil palynomorphs from the Precambrian to the Holocene for their usefulness in the relative dating and correlation of sedimentary strata. Palynology is also used to date and understand the evolution of many kinds of plants and animals.
[1]: 34 Since 1986, Bulletins has featured the series "Neogene Paleontology of the Northern Dominican Republic", a large-scale project to identify and collect fossils from the Neogene Caribbean sequence. 20 systemic monographs in the series have been published in Bulletins of American Paleontology.
