What is the term for the remains or traces of ancient life found in sedimentary rocks?

• A. Petrified remains
• B. Imprints
• C. Fossils
• D. Trace fossils

Answer: (C)

Fossils are the remains or signs of ancient life preserved in sedimentary rocks. This term covers both actual parts of organisms, like bones or shells that have become mineralized, and traces of life, such as footprints, burrows, or impressions that show an organism’s activity. While petrified remains are a specific kind of fossil where the organic material is replaced by minerals, and imprints or trace fossils are particular examples of fossil evidence, the general term that includes all of these possibilities is fossils.
