It would be carbonation.
Hope this helped:)
Fossils can be formed by:MummificationPetrificationDesiccationRelated question on Answers.com:How are fossils formed?
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.
Permineralized fossil are formed when dissolved minerals precipitate from a solution in the space occupied by the organism's remains.
That organisms were modified over time by a process called natural selection. The nonrandom survival and reproductive success of randomly varying organisms.
The way fossils are formed in very dry places is called mummification. Amber is a hardened tree sap, yellow to brown in color, and often a source of insect fossils.
Short spans of geologic time
Fossils are formed from the buried remains of marine organisms. These organisms are under a tremendous amount of pressure and, over time, they fossilize.

There are multiple methods of fossilization, but fossils generally are formed by rapid burial of organisms or traces of organisms by sediments. The website of the New York State Geological Survey offers a useful introduction to the differing processes of fossil formation. Please see the related link for details.
No. Basalt is an igneous rock usually formed from lava flows. Any organisms caught in the flow will be incinerated.
Imprints or impressions of such things as footprints or trails are generally referred to as trace fossils. Body impressions are called mold fossils, and molds that are filled in are called cast fossils.
Fossils will be found almost exclusively in sedimentary rocks. Sedimentary rocks are formed by the compression and cementation of sediments over millions of years. Organisms that die on, in, or near a body of water have a better chance of becoming fossils due to the fact that fossilization requires that the organism be covered relatively quickly in sediments. Once covered in sediments, some of these remains remain intact and can be discovered to have formed fossils or fossilized remains within the layers of the rock. Shale is a particularly good rock for this to occur in, and some limestones like chalk, are composed almost entirely of fossilized marine animal remains.false!sedumntary
fossils are small living organisms that existed millions of years ago. They mostly have a shell which is the fossil that you can sea. Sedimentary rock is formed when lots of small particles and pieces of rock and often dead organisms, (the fossils) drift down to the sea bed and over millions of years get compressed together to form the rock. The fossil that you see was once a living shelled organism which dies and was preserved as the sedimentary rock formed
by fossils
well because organisms can be preserved in sedimentary rock mispelled
just like all other fossils
Mineralization occurs in the original remains, inside the shells bones and teeth, of animals and fish. This process turns remains into fossils.
