Kivettyneenä
Kivettyneenä is a Finnish word that translates to "fossilized" or "petrified" in English. It refers to the process by which organic matter, such as bones, shells, or wood, is gradually replaced by minerals over geological time. This process typically occurs when an organism is buried rapidly, preventing decomposition, and is subjected to mineral-rich groundwater. The original organic material dissolves and is replaced by minerals like silica, calcite, or pyrite, preserving the shape and sometimes even the fine details of the original organism.
The result of this process is a fossil, which is essentially a rock that retains the form
