Fossilized remains

Fossilized remains are the preserved evidence of ancient life, such as bones, shells, teeth, or even traces like footprints. When an organism dies, its remains can become buried in sediment, where minerals gradually replace the organic material over time, turning it into rock. This process helps scientists understand the history of life on Earth, including how species evolved and interacted with their environment. Fossils can also reveal information about past climates and ecosystems, making them crucial for studying both biology and geology.
