How does fossil containing limestone form

The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble. Uses of marble: Building Stone

Many marine invertebrates like shells form fossils in this way. Amber can preserve organisms if they become trapped in tree resin. The resin will eventually harden to form a golden amber that has been shown to preserve fossils up to 100 million years old. Trace fossils record the activity of an organism.

Limestone is primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities. The purity of limestone depends on the geological conditions under which it formed. A limestone rock, from Southerndown in south Wales, containing fossil shells. (Gryphaea arcuata — Devil's toenails).

The two parts of the shell (the valves) are still attached to each other, and the bottom …

Limestone. Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock.

Limestones are composed of calcium carbonate and most all are formed from the accumulation of oceanic organisms that make their …Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils. As the layers of sediment build up on top of one another, they create a physical timeline. The oldest layers, along with the organisms that were fossilized as they formed, are deepest. The youngest layers are found at the top.

Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks:Start studying Earth Science Chapter 5 and 6.
