In some cases microbes control the phosphatization, and the remains of the microbes that feed on the preserved tissue form the fossil. In other, the tissue itself is the source of phosphate and its phosphatized remains form the fossil. In the intermediate case the phosphatized tissue retains the impressions of the phosphatizing microbes. [1]
Flint – Cryptocrystalline form of the mineral quartz; Concretion – Compact mass formed by precipitation of mineral cement between particles; Fossil – Preserved remains or traces of organisms from a past geological age; Petrogenesis – Processes that form rock
Preserved skin, salt-preserved or air-dried, can also be used in certain situations. [19] DNA preservation is difficult because the bone fossilisation degrades and DNA is chemically modified, usually by bacteria and fungi in the soil. The best time to extract DNA from a fossil is when it is freshly out of the ground as it contains six times the ...
This is a list of Ice Age species preserved as permafrost mummies. It includes all known species that have had their tissues partially preserved within the permafrost layer of the Arctic and Subarctic. Most went extinct during the Late Pleistocene extinctions while some are still extant today. They have been listed to the most specific known ...
The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself.

Well-preserved basal arthropod Opabinia from Burgess Shale Lagerstätte (Middle Cambrian) . A Fossil-Lagerstätte (German: [ˈlaːɡɐˌʃtɛtə], from Lager 'storage, lair' Stätte 'place'; plural Lagerstätten) is a sedimentary deposit that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues.
Fossil preparation is a complex of tasks that can include excavating, revealing, conserving, and replicating the ancient remains and traces of organisms. It is an integral part of the science of paleontology, of museum exhibition, and the preservation of fossils held in the public trust.
