Jälkifossiilit
Jälkifossiilit, also known as trace fossils, are geological records of biological activity rather than the preserved remains of the organism itself. These include structures like footprints, burrows, trails, borings, and coprolites (fossilized feces). Jälkifossiilit provide valuable insights into the behavior, movement, and diet of ancient life forms that might not have been preserved as body fossils.
The study of jälkifossiilit is called ichnology. Ichnologists analyze the morphology and context of these traces
Jälkifossiilit are crucial for understanding the diversity of life in past ecosystems, especially for soft-bodied organisms
