This can be a presentation software such as PowerPoint, or a video creator like Adobe Spark or Vyond. Rinse the fossil with warm, distilled water. When collecting at some sites where there are thousands of loose specimens, this will save much time. If you are preparing a hard, pyritized specimen, lightly brushing the surface with a soft brass brush can increase the fossil/matrix contrast and bring out a kind of metallic luster. Loose, sturdy fossils such as brachiopods that are collected from shale exposures can even be piled without wrapping in a tin can or a small box, if the container is packed full so that the contents do not rattle. Brush away any remaining dirt or leaves with a stiff-bristled brush. Rub the toothpaste into the rock in a circular motion, focusing on any heavily scratched areas. This step may be repeated if the stain appears to be going away and the color of the laminate has not been affected.

Use a dental drill with a very small bit, if necessary, to further remove small pieces of dirt, debris, and sediment. Handle fossils gently and use appropriate tools for extracting them from the ground. 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). If desired, paint the fossil replica to make it look more realistic. Repeat the process if the rock still needs additional polishing. Start by gently dabbing the stained fossil with a damp cloth and an appropriate cleaning solution. Too often a rare specimen has been damaged because its owner brushed varnish on it or destroyed fine detail by plunging the fossil in acid to get rid of matrix. The Burgess Shale refers to both a fossil find and a 505-million-year-old rock formation made of mud and clay. Place the rocks into the bucket and let them soak for 10 minutes or so. Biological activity - Fossils can also be destroyed by biological activity, such as scavenging animals, decaying bacteria, and algae.
