👉 Flinting, also known as a fossilized stone or rock, is an example of a sedimentary rock that has been weathered and transformed into a smooth, polished surface. This process occurs in the Earth's crust under extreme heat, pressure, and time, resulting in the formation of a smooth, flat surface. Fossilization refers to the transformation of materials from their original state or state of origin into an almost natural state due to environmental conditions such as temperature, pressure, and chemical reactions
