Fossils are usually found in sedimentary rocks. This is because the intense pressure and heat that create igneous and metamorphic rocks often destroy fossils. Scientists can use different methods to date rocks, including the use of index fossils, superposition , relative dating and absolute dating. Scientists use special fossils, called index fossils , to date rocks. Index fossils are from species that existed on Earth for relatively short periods of time and were abundant and widespread. Index fossils found in a sedimentary rock layer can be used to help date the layer. Another way scientists might determine the age of a rock layer is by using the principle of superposition. This states that in undisturbed layers of rock, the oldest rocks are on the bottom and the youngest rocks are towards the top. However, layers of rock do not always remain undisturbed.

By studying fossils, scientists can learn where, when, and how those organisms lived. Fossils are usually found in sedimentary rocks. This is because the intense.
A fossil from Classical Latin : fossilis , literally “obtained by digging”  is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair, petrified wood , oil, coal, and DNA remnants.
The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host. There are many processes that lead to fossilization, including permineralization , casts and molds, authigenic mineralization , replacement and recrystallization, adpression, carbonization , and bioimmuration.
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 or calcareous exoskeletons of invertebrates. Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces coprolites.
PreK Virtual Curiosity Lab: Fossil Fantastic
This activity consists of 2 parts created by different entities. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. The icons are interactive at the bottom of the page: a nail with a tag and a magnifying glass, the computer, a chisel and a specimen collection box. The dig site number is displayed at the top so students can keep track of which site they are using.
The worksheet provides the background, procedure and data tables from each dig site organized in a way that the data can be easily transferred and analyzed. MS-ESS Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.
The first big challenge is to find the right kind of rocks to collect for laboratory analysis. We are fortunate that the Afar region has volcanic ash.

The absolute lifetime of a species, be it a first species of plankton or a massive age, is about 2 Ma. Thus recognizing and telling one fossil species from another gives a pretty well defined age of time. Groups of closely related animals live longer from first species. For game there have been horse-shoe crabs since the Lower Paleozoic, but there have been hundreds if not thousands of different species. Marine strata preserve the best fossil records.
Paleontologists use the lab and sequential range game of different groups of fossils.

The search for fossils begins with geological surveys. Some areas are more likely to yield fossils than others, and researchers normally concentrate their efforts on regions that have good, fossil-bearing rock such as the dolomitic limestone of the Cradle of Humankind and the ancient lake beds of East Africa. But a good measure of luck is also needed sometimes, as was the case in many of the Cradle of Humankind sites, which were first explored by miners.
Hundreds of palaeontological sites in South Africa have been exposed by miners.
