Purists will balk at any type of preservative coating. Stay aware of your surroundings at all times. An emergency method that works well if conditions are favorable is to enclose a fragile fossil in a gob of wet clay or mud. You can also use a small paintbrush dipped in water or soapy water to gently scrub away the dirt. Let the fossil soak for about two minutes. Hardening agents can be applied to make fragile specimens more stable. Soak the sand dollars in the mixture for 20-30 minutes, or longer if necessary. Once the bones are completely dry, they can be coated with a protective finish. Apply a few drops of mineral oil to a clean cloth and gently rub the fossil. Remove the sand dollars from the solution and rinse them with cold water. If necessary, use a degreasing cleaner to remove any stubborn dirt or grime. Fossil leaves similar to modern ones are found in concretions of Cretaceous age that weather out of sandstones and shales in a belt extending from the Dakotas down into Kansas. Among the most common of these are algae such as Yuknessia, a form of green algae. Or colors can be matched with a mixture of cement pigment added to the Plaster of Paris, water putty, or epoxy. Warning: Finally, place the stones in the tumbler and fill it with a fine grit. work the fossils out of it. Others appear unrelated to any living forms and their later . Finally, carefully rinse the sample with distilled water to remove any remaining contaminants.

If there is still dirt or debris, you may need to boil the rocks in a pot of water for 10 minutes. A fossil found in several broken pieces can be reassembled roughly in a small square of aluminum foil. Allow it to soak for a few hours, then gently scrub the surface with a soft brush. If the mixture contains too much plastic, the fossil will become shiny, particularly if the fossil itself is composed of smooth, nonabsorbent, chiti-nous material, as trilobites or cephalopods are. This method is especially useful in keeping together the loose parts of a broken fossil. Begin by removing loose particles from the matrix with a soft brush or air vacuum. Soak the shells in a sink full of warm water and a few drops of mild dish soap. Use a basic hand-held garden trowel or a small shovel to gently scrape away loose leaves and dirt from the surface of the rocks. These units yield over 80 species of macrofossils and are particularly rich in brachiopods and bryozoans. Loose, weathered specimens taken from the bottom of a slope should be kept separate from those taken directly from an identifiable rock unit. Finally, apply a small amount of mineral oil to the fern to help preserve it. Looking at relative electric prices vs renewable penetration among various state is instructive. Soak them for 30 minutes. Using a soft-bristled brush, scrub the ammonite gently to remove any remaining dirt and debris. The fossil should then be examined and documented to provide a permanent record of the specimen. This process, called hydraulic fracturing or fracking (sometimes referred to as unconventional production ), breaks up the formation, releases the natural gas from the rock, and allows the natural gas to flow to and up wells to the surface. Specimens on the surface of soft shales cannot be cleaned in water. Make sure the storage container is well-ventilated to prevent moisture build-up. If the ammonite fossil has a lot of cracks or erosion, you may want to consider sealing the fossil with a wax or oil to protect it. At home, the actual work of cleaning fossils will begin: clinging matrix can be removed or trimmed to size, and rock can be dissolved or otherwise eliminated to free its content of small fossils.

Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick). The carefully unwrapped specimens will need a bath or more extensive cleaning before they can be properly studied or displayed. Allow the fossil to completely dry before applying a coat of a conservation grade wax. Cut a piece of cotton or linen fabric to fit the base of the fossil, then carefully place it on top and secure it with pins. For the most part, bleach is not a good idea for cleaning and preserving fossils. Almost all fossils are preserved in sedimentary rock. Rinse the shells with fresh water and allow them to air dry. Use a consolidant - This is a chemical solution that can be applied to the sandstone. Chemical reaction - Fossils can also be altered or destroyed by chemical reactions resulting from the oxidation of organic material or acidic groundwater. Rinse the fossil slab and buff it again with a clean, oiled cloth. Immersion will make the shale stronger. This can help preserve the fossil and enhance the beauty of the details.
