Shelly limestone is a highly fossiliferous limestone, composed of a number of fossilized organisms such as brachiopods, bryozoans, crinoids, sponges, corals and mollusks. It varies in color, texture and hardness. Coquina is a poorly indurated form of shelly limestone. Shelly limestone is a sedimentary rock because it is made up of fragments.Furthermore, some rock units are made up of beds of alternating compositions, such as within some of the strata units in the Cincinnati area which consist of alternating beds of limestone and shale (figure 5).10 Sometimes these thinner beds thicken and thin even within the outcrop scale of a road cut. So whereas we do find neat, uniform fossil ...Fossils are prehistoric remains or traces of plants or animals preserved in sedimentary rocks, and there are several types found in nature. Some of the plants or animals existed millions of years ago. Fossils are found throughout the world in sedimentary rocks such as sandstone, limestone or shale.

Sedimentary rock - Limestones, Dolomites, Calcite: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of …

While there’s no such thing as petrified rock, petrified wood is fossilized wood. According to YourGemologist, there is no wood actually left in petrified wood, only rock that takes the same form and shape of the wood.Their formation can be the result of localized precipitation due to small differences in composition or porosity of the host rock, such as around fossils, inside burrows or around plant roots.

Limestone (calcium carbonate CaCO 3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO 3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place ... Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor.
