Some of it does.
A limestone that contains fossils would be classified as an organic sedimentary rock because the fossils are of biological origin.
Paleontologists are looking for fossils in sedimentary rock.
True. Vinegar contains acetic acid which can dissolve the calcium carbonate in limestone, making it possible to separate the fossils from the limestone.
limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.

Limestone is a biochemical rock that can contain fossils. It is formed from the accumulation of calcite or aragonite shells or skeletal fragments of organisms such as corals, foraminifera, and mollusks. Over time, these remains can be compressed and preserved in the rock.
Chalk - however, the fossils are microfossils called Coccolithophores. Limestone is a soft sedimentary rock, not exactly "crumbly" like chalk but more likely to contain fossils visible to the naked eye.
Fossils are frequently found in shales.
Fossils are nearly always found in some type of sedimentary rock. Limestone is a sedimentary rock which very commonly contains fossils, as is coal.
Fossils.
Fossiliferous limestone has larger fossils in the rock and is of biochemical composition where as the oolitic limestone doesn't have any fossils and has a chemical composition. The Oolitic limestone has spherical grains that resemble miniature pearls (they are called ooliths or ooids). Both do effervesce in diluted HCL(acid)
of course its a rock.
