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 If the fossil has been replaced by silica, it could be removed by the application of acid to remove the limestone that surrounds it.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
Most fossils form in sedimentary rock, which is created by the deposition and accumulation of sediments over time. The most common types of sedimentary rock that preserve fossils are shale, sandstone, and limestone.
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.
Paleontologists study prehistoric animal and plant life remains found in fossils.
Paleontologists are looking for fossils in sedimentary rock.
Fossils are frequently found in shales.
Some of it does.
Fossils.
A limestone that contains fossils would be classified as an organic sedimentary rock because the fossils are of biological origin.
of course its a 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 up out of fossils of corals and shells from the water.
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
Sedimentary, especially limestone.
limestone is made underwater from the shells of animals. We know this because limestone also contains many fossils.
