Give two factors which aid the fossilization process, explaining how each increases preservation potential.

Rapid burial of the organic material will prevent any erosion or scavenging occurring, allowing the organic material to become encased in rock and become more likely too be preserved.Becoming buried in fine grained sediments, such as clays or shales, allows for greater ease of preservation as there will be less influence of percolating pore waters and aerobic organisms that degrade the biological material. Burial in a low energy environment prevents disturbance of the organic material which will produce a higher number of more complete fossil remains.Low oxygen/anaerobic conditions prevent the action of many detritivores which would breakdown the organic remains and so leaving a greater proportion of the organic material to become fossilised. The composition of the organisms body effects preservation potential, with organisms containing harder elements such as bones, teeth and scales, and more decay resistant substances such as pigments being more likely to become preserved.
