A fossil formed when organic material is preserved as a thin film of carbon is created when the volatile components of an organism decay, leaving behind only a carbon residue that outlines the original form. This process often occurs when an organism is buried under sediment and subjected to pressure and heat, which drive off the liquids and gases. A common example is the preservation of plant leaves or delicate insect wings, where the fine details of the original structure are visible in the carbonized outline.
This type of fossilization provides valuable insights into the morphology and structure of ancient organisms, especially those that lack hard parts. Because even intricate details can be preserved, researchers can study the anatomy and evolutionary relationships of extinct species. Historically, its study has contributed significantly to our understanding of past ecosystems and the development of life on Earth, enabling paleontologists to reconstruct ancient environments and track the evolution of various plant and animal groups.
