HOW ARE FOSSILS FORMED & FOUND? 1. An animal dies. Fossils form best if the carcass is covered quickly with sediment (water and mud). 2. The flesh rots away, and the bones are slowly covered with layered sediment. 3. "Permineralization" occurs if some or all of the original material remains, but has been strengthened by minerals that were dissolved in the water that soaked into the bony structure. 4. "Petrification" occurs if water that contained minerals soaks into the pores of the bony structure, entirely replacing them with minerals. 5. Weathering. Earth movements and/or erosion, cause the fossil to become exposed. Whatever COLOR of the minerals in the sediment that covers the animal, that is the color the fossil will become! Here is a chart that will identify the colors of the minerals:
