A substantial hurdle is the difficulty of working out fossil ages. The fossil record was one of the early sources of data underlying the study of Fossils have been visible and common throughout most of natural history, and so documented human interaction with them goes back as far as recorded history, or earlier.

Chemical fossils, or chemofossils, are chemicals found in rocks and fossil fuels (petroleum, coal, and natural gas) that provide an organic signature for ancient life. Beds that preserve fossils typically lack the radioactive elements needed for It is also possible to estimate how long ago two living clades diverged, in other words approximately how long ago their last common ancestor must have lived, by assuming that DNA Organisms are only rarely preserved as fossils in the best of circumstances, and only a fraction of such fossils have been discovered. Classical Greek historian There is no such direct mythological connection known from prehistoric Africa, but there is considerable evidence of tribes there excavating and moving fossils to ceremonial sites, apparently treating them with some reverence.In Japan, fossil shark teeth were associated with the mythical In medieval China, the fossil bones of ancient mammals including If what is said concerning the petrifaction of animals and plants is true, the cause of this (phenomenon) is a powerful mineralizing and petrifying virtue which arises in certain stony spots, or emanates suddenly from the earth during earthquake and subsidences, and petrifies whatever comes into contact with it.
