For fossils as old as dinosaurs (over 65 million years), the conventional wisdom has been that no original proteins from once-living cells could remain. If the delicate structure of soft body parts is discernable in a fossil, that is normally because these parts were converted to some type of hard mineral during the fossilization process.. Itouchmyself song
Another example is the footprints left by dinosaurs along an ancient river or the hollow tubes created by worms burrowing in soft mud in an ancient ocean. There are more trace fossils than body fossils because one organism can leave behind many traces (e.g. footprints), but only one set of hard parts (e.g. bones) to become a fossil. As already mentioned, the ideal conditions for fossilization are immediate burial in hypoxic, mineral-rich sediments in a low temperature environment. These elements make the existence of fossils rare. Four types of process contribute to the formation of a fossil. These are mineralization, carbonization, encrustation and distillation.Permineralization is a process of fossilization of bones and tissues in which mineral deposits form internal casts of organisms. Carried by water, these minerals fill the spaces within organic tissue.
