Yes, mostly gravel from a landslide, and organic rocks
Rock that is made from cemented animal bones and shells is what organic limestone is.Specifically, the term "organic" indicates that the rock in question contains parts from a once-living animal. Hard parts such as bones and shells may cement together. The minerals - such as calcite - which make up these hard parts will form into limestone. In comparison, chert will form from the silica-based skeletons of microorganisms that die in such watery environments as lakes and oceans.
The rock would be limestone, the mineral would be calcite.
Conglomerate consists of cemented pebbles of various sizes.
Coquina is a sedimentary rock made up of shells, shell fragments, and skeletons of small marine creatures.
Limestone is a boigenic rock. It is formed as a byproduct of living things, frequently it is made from the calcareous skeletons of living creatures. If we take the Chalk as a limestone, this was made in a warm shallow sea from the shells of microscopic plankton as they died and sank to the sea floor. However along with the calcareous shells, there were also shells of diatomic plankton which are made out of silicon dioxide (quartz). After deposition as the chalk was compacted by the overlying sediments that were laid down on top of it and it became buried, the water it contained became heated and the skeletons of the silicious diatoms dissolved in the water and then were redeposited as layers of "Chert" or "Flint" in the Chalk.
Limestone made from shells would be an organic sedimentary rock.
Limestone and chalk.
Limestone made from shells would be an organic sedimentary rock.
Limestone is not generally referred to as an organic rock. It is primarily composed of calcium carbonate, which is a mineral. However, in some cases, limestone can contain remnants of organic matter such as shells, coral, or other marine organisms, which can give it a slightly organic origin. This is why some people may refer to limestone as an organic rock.
Limestone
carbonaceous shells form limestone which in this case is a bio-chemical sedimentary rock
Any Type Of Limestone
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.
