Clean the fossil with a soft brush and a mild detergent. The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. Trim the matrix: Use the rock saw to trim the edges of the matrix to the desired shape. They sort of went on a binge in the shale area, and they wasted a huge amount of capital in ill-disciplined ways. It's much faster! Make sure to evenly distribute the paste over the rocks, so they receive a consistent polish. The Burgess Shale fossils as a group have already developed into a variety of sizes and shapes from the much simpler, pre-Cambrian life forms. Make sure the storage container is well-ventilated to prevent moisture build-up. Use drilling and blasting to break up the material and reduce the size of the overburden. Place the shells in a strainer and soak them in a mixture of 1 part white vinegar and 2 parts water for an hour. Powered by Invision Community.

The fossil teeth should be firmly embedded in the resin and easy to handle. Repeat the process if the rock still needs additional polishing. Hardening agents can be applied to make fragile specimens more stable. Heavier particles sink and form sandstone and limestone, while clay and fine silt remain suspended in water. Place the fossil in the plastic container and fill with enough white vinegar to cover the fossil. Repair: If the ammonite is cracked or broken, use a clear epoxy or two-part marine epoxy to repair it. Use a soft brush to brush away any remaining particles. Bony fossils are encased in a rock jacket, but by the time the bones weather free they have become bone meal. Rinse the skeleton under cool running water to remove any remaining flesh, organs, and tissue. Rinse the shells in fresh water and dry them off with a soft cloth. Shales that enclose plant fossils seem to be particularly weak, though fragile invertebrate fossils that must have supporting matrix, such as trilobites, graptolites, and bryozoans, often occur in crumbling shales. This step may be repeated if the stain appears to be going away and the color of the laminate has not been affected. Finally, if desired, you can use a dry cloth to apply a small amount of mineral oil to the fossilized specimen. Nylon is softer than the calcite substance of fossils and softer than the matrix, too. Stay informed of local weather forecasts and other safety hazards. Place the shells in the sun to dry completely. If the fossils have deep nooks and crannies, grains of the wood have an annoying tendency to lodge there, but they can be picked out.
