Nounfossils
From Wiktionary under the GNU Free Documentation License. Fossils (from Latin fossus, literally "having been dug up") are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record. The study of fossils across geological time, how they were formed, and the evolutionary relationships between taxa (phylogeny) are some of the most important functions of the science of paleontology. Such a preserved specimen is called a "fossil" if it is older than some minimum age, most often the arbitrary date of 10,000 years ago. Hence, fossils range in age from the youngest at the start of the Holocene Epoch to the oldest from the Archaean Eon several billion years old. The observations that certain fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century. The development of radiometric dating techniques in the early 20th century allowed geologists to determine the numerical or "absolute" age of the various strata and thereby the included fossils. Like extant organisms, fossils vary in size from microscopic, such as single bacterial cells only one micrometer in diameter, to gigantic, such as dinosaurs and trees many meters long and weighing many tons. A fossil normally preserves only a portion of the deceased organism, usually that portion that was partially mineralized during life, such as the bones and teeth of vertebrates, or the chitinous exoskeletons of invertebrates. Preservation of soft tissues is rare in the fossil record. Fossils may also consist of the marks left behind by the organism while it was alive, such as the footprint or feces (coprolites) of a reptile. These types of fossil are called trace fossils (or ichnofossils), as opposed to body fossils. Finally, past life leaves some markers that cannot be seen but can be detected in the form of biochemical signals; these are known as chemofossils or biomarkers. From Wikipedia under the
GNU Free Documentation License What kind of Fossils can I find at the Duck Creek formation? Q. I want to know at the Duck creek formation of Texas and Oklahoma what kind of fossils can you find. I want to know because I want to visit the place soon and I want to know what I can find there. Asked by skater boy - Sun Jul 15 12:14:49 2007 - - 2 Answers - 0 Comments A. The Duck Creek Formation is a Cretaceous limstone. It looks like the fossils you are most likely to find are ammonite, gastropods, and echinoids. You might also try looking up some of the paleo and geology groups around the area you are going to because they can be a good resource. Here are some good websites to look at: this one has some good localities Answered by Kelli W - Sun Jul 15 12:28:05 2007 Where are some places in California that I could look for fossils? Q.

The exterior of the Hewlett Building on the Stanford Campus is covered with mudstone with lots of bivalve and gastropod mollusk shells. It's very cool, but most students pass by without even noticing. You can go to the Valley Life Sciences Building on the Berkeley campus. There are displays of some really great fossils including a cast of a T. rex. Answered by scottsdalehigh64 - Fri Jun 27 13:43:16 2008 What is other evidence of extinction of species besides fossils?
