What is mold fossil?

Mold fossils are the traces of organisms that have left impressions, shapes, or imprints in rock. They are typically found in sedimentary rocks and can include imprints of shells, bones, or plant leaves, as well as other organic materials.

Mold fossils are formed when an organism dies and its remains are buried in sediment that eventually hardens into rock. The soft parts of the organism decay, leaving behind an imprint or impression that captures its shape and some of its features.

Mold fossils can be important sources of information about past life on Earth, particularly when combined with evidence from other types of fossils. They provide clues about the morphology, behavior, and ecology of extinct organisms and can help scientists reconstruct the history of evolution and environmental change. However, mold fossils are typically less informative than complete or partially complete specimens, such as body fossils or trace fossils that preserve more of an organism's anatomy and behavior.
