👉 Paleothnology is a branch of science that studies the structure and composition of rocks, minerals, fossils, and other materials from ancient times. It focuses on understanding how these materials were formed, what they contained, and how they have been altered or modified over time. Paleothnologists use various methods to study these materials, including radiometric dating, chemical analysis, and fossil analysis. This field has applications in fields such as archaeology, geology, biology, and environmental science.
