    Fossils Overview

    • Fossils represent the preserved remains of ancient plants and animals.
    • Formation occurs when bodies are buried in sediments, primarily sand and mud.
    • Ideal burial locations include ancient seas, lakes, and rivers.

    Fossil Characteristics

    • Fossils serve as crucial evidence of past life on Earth.
    • They can provide insights into prehistoric ecosystems and species interactions.
    • Typically, only remains that are over 10,000 years old qualify as fossils.
