About Fossil See Fern Plates: The white color of these detailed fern fossils contrasts well against the black shale they are preserved in. These plants were buried in a swamp where a low temperature, pressure, and oxygen environment the plant tissue was slowly replaced by pyrite. This pyrite was later replaced by a whitish mineral (aluminum silicate) as the fossils were buried and exposed to the heat and pressure inside of the earth.
