FOSSIL



FOSSIL is a standard for allowing serial communication for telecommunications programs under DOS. FOSSIL stands for ''Fido Opus Seadog Standard Interface Layer'' and was made by a group of Fidonet sysops to make their software work on different machines. ==External link== * [http://www.bbsdocumentary.com/research/PROGRAMS/NETWORK/FOSSIL/fsc-0015.txt Fundamentals of FOSSIL implementation and use] Computer and telecommunication standards

Fossil



Subpages will soon follow --User:Arco Scheepen Under living fossils, I don't think horseshoe crabs have ever been thought extinct. I think it's more of an issue of a living creature that has characteristics more in common with ancient critters than with modern ones. Jawless fishes like lampreys might also count. --User:Belltower ----- Ok, will change the text tonight --User:Arco Scheepen ----- We might also want to consider having a ":Fossil record" page, talking about how geology and fossils interact to give us a timeline, and move the timeline to that page -- or even another one. The evolution of life on earth is deserving of its own page, with links from fossils and other places. ----- Good idea, we could try to set up something like :Geologic Timescale --User:Arco Scheepen ---- I'm curious how the :Horseshoe crab was ever thought to be extinct! They wash up by the hundreds on :Florida beaches! --User:Dmerrill : I agree. They are everywhere. I saw some along the coast of China. Horseshoe crabs fall under the ''not resembling any other living species'' part of the definition, not the ''once thought to be extinct'' part. ==Invitation== Work is currently in progress on a page entitled Views of Creationists and mainstream scientists compared. Also currently being worked upon is Wikipedia: NPOV (Comparison of views in science) giving guidelines for this type of page. It is meant to be a set of guidelines for NPOV in this setting. People knowledgable in many areas of science and the philosophy of science are greatly needed here. And all are needed to ensure the guidelines correctly represent NPOV in this setting. :) User:Barnaby dawson 21:42, 29 Dec 2004 (UTC) == microfossil == microfossil redirects here, but there's nothing about them! :'-( - User:Omegatron 18:58, Jan 5, 2005 (UTC) Any information on how long it takes for a fossil to form? User:Crazyeddie 07:30, 5 Feb 2005 (UTC) == Pic == I believe the picture that says "Fossil plants" is actually a dendrite, and not a real fossil. --User:DanielCD 19:17, 2 Mar 2005 (UTC) Pic has been re-captioned and moved to appropriate spot. --User:DanielCD 16:35, 3 Mar 2005 (UTC) : Yes that's very possible. I just wanted to contribute the photograph which I had taken, but I am not competent in paleotology. I am happy that someone cares to examin it ! :) User:Rama 16:56, 3 Mar 2005 (UTC)

Fossil



:''For other uses of the term, see Fossil (disambiguation)'' [[Image:Igammonite.jpg|thumb|A fossil Ammonite]] Fossils are the mineralized remains of animals or plants or other traces such as footprints. The totality of fossils and their placement in Rock (geology) formations and sedimentary layers (Stratum) is known as the fossil record. The study of fossils is called paleontology. The word fossil is derived from the Latin word ''fossilis'', which means "to be dug up". [[Image:Knightia.jpg|left|thumb|250px|Fossil fish of the genus ''Knightia'']] Fossilization is actually a rare occurrence because natural materials tend to be recycled. In order for an organism to be fossilized, the remains normally need to be covered by sediment as soon as possible. However there are exceptions to this, such as if an organism becomes petrifaction or comes to rest in an anoxic environment such as at the bottom of a lake. There are several different types of fossils and fossilization processes. Fossils usually consist of traces left by the remains of the organism itself. However, fossils may also consist of the marks left behind by the organism while it was alive, such as the footprint of a dinosaur or reptile. These types of fossil are called trace fossils. The oldest known structured fossils are most likely stromatolites. Believed to be formed by the entrapment of minerals by mucous-like sheets of cyanobacteria, the oldest of these formations dates from 3.5 billion years ago. Fossilized deposits of heavy carbon (acritarchs) that are also indicative of earlier life (3.8 billion years ago) are currently proposed as the remains of the earliest life on Earth. ==Permineralization== [[Image:Trilobite2.jpg|thumb|A permineralized trilobite, ''Asaphus kowalewski'']] Permineralization consists of organic remains turning into stone. The organism gets covered by sediment soon after death or after the initial decaying process. The degree to which the remains are decayed when covered determines the later details of the fossil. Some fossils only consist of skeletal remains or teeth; other fossils contain traces of skin, feathers or even soft tissues. Once covered with sediment, these layers slowly compact to rock, after which the chemicals in the remains are slowly replaced with hard minerals. Although the original chemical composition of the organism has entirely vanished, the mineralization process proceeds differently for different kinds of tissues, and microscopic details of internal bone structure may be preserved. Not all dead plants or animals turn into fossils. The youngest fossils, except for certain special cases like freezing or preservation in tar pits, are believed to be at least 10,000 years old. [http://clearlyexplained.com/nature/earth/minerals/fossils.html] ==Mould, cast and trace fossils== If percolating water dissolves the remains of an organism, and thereby leaves a hole in the matrix rock, the result is called a ''mould fossil''. If this hole is filled with more minerals, it is called a cast fossil. If the burial of the organism was rapid, then chances are that even impressions of soft tissues remain. Trace fossils are the remains of trackways, burrows, footprints, Egg (biology)s and egg-shells, nests and droppings. The latter, called coprolites, can give insight in the feeding behavior of animals and can therefore be of great importance. ==Resin fossils== Smaller animals, insects, spiders and small lizards can be trapped in resin (amber), which is secreted from trees. These fossils can be found in sandstones or mudstones or washed up on beaches like those around the Baltic Sea. ==Pseudofossils== [[Image:Fossile_J_3.jpg|thumb|Example of a pseudofossil: this dendrite looks much like a plant]] Pseudofossils are regular patterns in rocks that are produced by naturally occurring processes. They can easily be mistaken for real fossils. Some pseudofossils, such as Dendrite (crystal)s, are formed by naturally occurring fissures in the rock that get filled up by percolating minerals. Other types of pseudofossils are kidney ore (round shapes in iron ore) and Agates, which look like moss or plant leaves. Concretions, round or oval-shaped nodules found in some sedimentary strata, were once thought to be dinosaur eggs, and are often mistaken for fossils as well. ==Living fossils== Living fossil is a term used for any living species which closely resembles a species known from fossils, i.e., as if the fossil had "come to life". This can be a species known only from fossils until living representatives were discovered, such as the Coelacanth, or a single living species with no close relatives, such as the Horseshoe crab, that is the sole survivor of a once large and widespread group in the fossil record. ==See also== * Acritarchs * Collecting fossils * Fossils and the geological timescale * Fossil fuels * Prehistoric life * Transitional fossil ==External links== * [http://www.fossilmuseum.net/index.htm The Virtual Fossil Museum throughout Time and Evolution] Fossils Paleontology fa:سنگواره ta:தொல்லுயிர் எச்சம்
