What is an organic sedimentary rock composed of cemented shells?
Coquina is an organic sedimentary rock composed primarily of cemented shells of marine organisms.
Cemented shells of marine organisms form which kind of sedimentary rock?
Bioclastic sedimentary rock--coquina.
Why is coquina classified as an organic rock with a granular texture?
Because it forms from animals that were once living which makes it an organic sediment. It can also be classified into the Detrital sedimentary rock category because it is compacted together.
A rock formed from living organisms?
Many rocks can contain fossil organisms. Generally speaking, sedimentary rocks are the rock type that contains the most fossil organisms. Coquina, a type of limestone, is formed nearly completely by the shells of marine organisms. And coal is a sedimentary rock composed of the remains of ancient swamp plants.
Where do you find siltstone?
Siltstone is a sedimentary rock that formed in ancient marine environments. Shale was also formed this way and is a sedimentary rock.

Bioclastic sedimentary rock--coquina.
Many caves in the eastern US were formed with what kind of sedimentary rock that contained remains of ancient marine life?
I believe it is Bioclastic sedimentary rock--coquina although it was formed by shells of marine organisms.
Is Oil formed from the accumulation of dead marine organisms and found in sedimentary rock layers?
In the most basic of terms, yes.

What is liquid from the remains of marine organisms?
Fossils are formed from the buried remains of marine organisms. These organisms are under a tremendous amount of pressure and, over time, they fossilize.
Many limestones are of biochemical origin?
limestones are organic sedimentary rocks formed from the accumulation and deposition of the hard part(skeletal part) of marine organisms. They are surfacial rocks formed at low temperatures and pressures.
How do you know that rock in some mountains formed under water?
Rock which has formed under water and is now appearing on the surface in mountainous areas would exhibit characteristics of sedimentary rocks found in marine settings: strata, marine fossils, and cemented sediments of various sizes and chemistries. Ripple marks could also be present.
How do shelled marine organisms contribute to the carbon cycle?
They form sedimentary rocks
Where is limestone formed in the earths crust?
Limestone started as the shells of marine animals. It started at the floor of the ocean and, layer-upon-layer, the shells became compressed and cemented together to form the sedimentary rock.
