Additionally, it references several scholarly works on geology and physics, including a 1982 bulletin, a 2014 book by David L. Goodstein, a 2018 study by Mulcahy et al., and a 2015 paper by Wakabayashi, providing citations for further exploration of the subject.

Fossilization, a rare process influenced by decay and environment, includes methods like permineralization and molds. Key fossil sites offer insights into ancient organisms and evolutionary changes. Fossils help trace Earth's history, indicate past climates and environments, and document significant events, such as mass extinctions.
