Fossil limestone rock

It is oolitic limestone, otherwise known as “egg stone” and close up the surface of the stone has a remarkable appearance. Made up of tiny spherical shapes. Picture credit: Everything Dinosaur. The powerful digital camera on the Smartphone can pick up fine details such as the small, bubble-like appearance of the surface of the limestone.

Most of the fossils I hunt are either in chalk (soft limestone), limestone, or a chalk/calcite combination. If i determine the fossil is able to be, or desired to be removed, I start with a dremel with a carbide bit. I take out the obvious rock and stay very clear of the fossil. Once I get closer to the fossil, I switch to a more precise ...This sample of limestone is composed of carbonate minerals, and formed in a shallow ocean. On the surface of the rock are million-year-old fossils of Vivapara contectoides. Limestone is an important reservoir for carbon. AMNH collectionLimestone has long fascinated earth scientists because of its rich fossil content. Much knowledge of the Earth’s chronology and development has been derived from the study of fossils embedded in limestone and other carbonate rocks. Limestone also has considerable commercial importance. Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces. The fossils in these rocks may be of macroscopic or microscopic size. Cliffs and dried river beds are also places to find fossils—any place where natural or unnatural forces have cut into the land might yield a fossil. 4. Limestone. Limestone is made mainly of calcium carbonate and dolomite. In some cases, limestone is a fossil.

Fossils are most common in limestones. That is because most limestones consist partly or mostly of the shells of organisms. Sometimes, however, the shells are worn so much that they look like sediment grains rather than "real" fossils. Fossils are also common in shales, which form from muds.First discovered by Belsazar Hacquet in 1778, Limestone is a sedimentary rock composed chiefly of calcite, CaCO3, and constitutes 10% of the total volume of all sedimentary rocks.

Thus, limestone has a combination of organic (Carbon-CO2) and minerals (Chiefly Calcium) along with other non-organic ions/minerals. The infusion of an organic substance with nMarble is a metamorphic rock formed by the alteration of limestone by heat and pressure. The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow.

Limestone ( calcium carbonate CaCO3) 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 CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.The specimen on the lower right is an approximately 80 million-year-old fossil dinosaur egg from the Late Cretaceous Djadochta Formation of Shahbarakh Usu, Mongolia.
