[Q]: - The soft tissue decomposes - The bones are left behind - Scavengers tear the body apart and move the bones elsewhere - Wind and rain also scatter the bones further - The bones left behind will weather and become buried by sand and soil - The proteins in the bone are replaced with minerals that are dissolved in the soil - This creates a rock-like substance called a fossil - Water and wind erosion wear away the layers of soil on top of the fossil - This makes discovery of the fossil possible. What might be the first step of the process?
