Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary...
Yea that's it :P
You are most likely to find them in sedimentary rock.
No, limestone is a sedimentary rock that is the basis for marble if it is compressed by millions of years of pressure. Limestone consists of calcium carbonate, CaCO3. Limestone dissolved in slightly acidic water forms the basis of stalactites and stalagmites in limestone caves.
Shale is made from layers of mud and clay pressed together. :)
A True form fossil is a fossil of the whole/entire body of the organism.
This is called a trace fossil. or a mold.
fossil rich limestone is made by the earth and is enhance with fossils although the chemical is man made, the two are basically the same.
The type of sedimentary rock in which the older rocks, unless disrupted, are on the bottom is called a fossil-rich limestone. This rock contains fossil remains of prehistoric organisms.
The limestone containing a fossil would be heaated to a sufficiently high temperature (about 1,800 centigrade).then the limestone would become powder and the fossil which is not as sensitive to heat as limestone would remain un damaged
If the fossil is replaced with silica the easiest way to remove the limestone is with weak acid such as vinegar. If the fossil is also limestone the best way to free it is by carefully removing the limestone with small picks and drills. This is usually best left to expert conservators as it can be delicate work.

Limestone is not a fossil fuel because it is not made from the carbon-containing soft tissues of long dead plants and animals. It is formed by fossils based on animal shells. Limestone is not used as a fuel but is used by industries for other purposes.
The Midwest region of the United States, particularly in states like Iowa, Illinois, and Kansas, is known for having rich fossil beds. These areas were once covered by ancient seas, which preserved a wide variety of marine fossils that can be found in limestone deposits and shale formations.
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
Calvert Cliffs consist of sedimentary rocks, primarily sands, clays, and fossil-rich limestone. These rocks were deposited over millions of years during the Miocene epoch.
In most cases both the limestone AND the fossil will be dissolved by the vinegar (eg a crinoid in Carboniferous limestone), so no. However, some fossils (eg echinoderms in the Chalk) are silicified and in these cases dissolving the limestone in vinegar will expose the fossil in spectacular detail and in other cases the fossil will dissolve more slowly than the matrix, so yes. . In other words there is NO true or false answer, fossil preparation and conservation is a discipline in itself.
Fossil Fuels =)
Iron-rich limestone can range in color from rusty red to brown or yellow, depending on the amount of iron present. The iron minerals in the limestone can oxidize and create different hues of color.
