Ichnogenus
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxa'' comes from the Greek ίχνος, ''ichnos'' meaning ''track'' and ταξις, ''taxis'' meaning ''ordering''.Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble each other in morphology but have subtle differences. Some authors have constructed detailed hierarchies up to ichnosupe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trace Fossil
A trace fossil, also known as an ichnofossil (; from el, ἴχνος ''ikhnos'' "trace, track"), is a fossil record of biological activity but not the preserved remains of the plant or animal itself. Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually altered by later chemical activity or mineralization. The study of such trace fossils is ichnology and is the work of ichnologists. Trace fossils may consist of impressions made on or in the substrate by an organism. For example, burrows, borings (bioerosion), urolites (erosion caused by evacuation of liquid wastes), footprints and feeding marks and root cavities may all be trace fossils. The term in its broadest sense also includes the remains of other organic material produced by an organism; for example coprolites (fossilized droppings) or chemical markers (sedimentological structures produced by biological means; for example, the formation of stromatolites).

Carnets De Géologie
''Carnets Geol.'' (previously ''Carnets de Géologie'' or ''Carnets de Géologie - Notebooks on Geology'') is an electronic journal that publishes in the field of geosciences, and particularly paleontology, stratigraphy, and sedimentology. The open-access journal is one of the founding members of the OA portal Geoscience e-Journals. Since 2007, it is published by the eponymic Association Carnets de Géologie at the University of Western Brittany in Brest, France. Description ''Carnets Geol.'' publishes peer-reviewed contributions (memoirs, articles, and letters) on an irregular basis, that is each new paper is released online as soon as possible after the editorial office received the latest reviewed and corrected version from the author(s). These contributions are written either in English, French, or both languages, but articles in Spanish, German, or Italian will also appear. All include titles, abstracts, and keywords in both English and French. In addition to the journal iss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
