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 rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). The Solnhofen Limestone or Solnhofen Plattenkalk, formally known as the Altmühltal Formation, is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies. The most familiar fossils of the Solnhofen Plattenkalk include the early …Carboniferous Limestone exposed at Ogmore-by-Sea, Wales.Carboniferous/Jurassic unconformity.

The fossil debris of coquina is composed of calcium carbonate, making coquina a variety of limestone. Coquina contains very little silt or clay-size particles, and its fossil fragments are lightly cemented together. This makes it an extremely porous rock that can serve as an aquifer for community and private water supplies.

Uses of limestone. Professor Cam Nelson. Scientifically, you know, limestone is important because it contains many fossils, and those fossils can be used to date the rock so that the geological period of time in which the limestone’s formed can be determined. The same fossils can tell us a lot about the environment in which the limestone formed.

It is also a good idea to look for signs that the rock contains a fossil before trying to break it, part of a fossil may be visible on the surface of the rock. You can identify the limestone by it's lighter grey colour and hardness, it should be quite hard to break without a hammer. It is however possible to find ammonites in the shale and ...Ammonite fossils are the preserved remains of ammonoids, which were marine creatures with a spiral shell that resembled a ram’s horn.

However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present.The calcite crystals in the rock are tiny when the transition from limestone to marble begins. The crystals grow larger with time and become recognizable as interlocking calcite crystals. This recrystallization process stops fossil and sedimentary structures of the limestone.
