It depends on their size and chemical composition. Fossils closely akin to the limestone matrix in composition would need to be manually removed by use of dental tools, scrapers, or electric Dremel type tools. If the fossil has been replaced by silica, it could be removed by the application of acid to remove the limestone that surrounds it.
550 million years old
There are many things one could do with catnip extract. One would be able to give the extract to their cat or place the extract on one of the cat's toys.
Fossils have layer upon layer of hardened tissue. Therefore they are quite rough in texture where the insides are more malleable. Depending on what the fossil is of some fossils give off a sour aroma. Most of the time animal fossils deteriate at a faster rate than fossils of humans or shells. Fossils are a unique study and I you study them further.
People want to know about fossils because fossils are history and tell us about history, and a lot of people find history fascinating.
Paleontologists study prehistoric animal and plant life remains found in fossils.
Fossils are frequently found in shales.
Some of it does.
Fossils.
of course its a rock.
Limestone is made up out of fossils of corals and shells from the water.
Limestone ;) <3
limestone is commonly used because it is easy to extract and carve
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
Paleontologists are looking for fossils in sedimentary rock.
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)
Sedimentary, especially limestone.
sedimentary rocks are what fossils are found in
