Their presence on archaeological sites is used to date the soil layers and the objects and events they are associated with and thus contributes to refine the chronology of sites. Temperatures from Fossil Shells 'An example of the ingenious technical work and hard-fought debates underlying the main story is the use of fossil shells to find the temperature of oceans in the distant past. As an example Pinnacle Point 's caves, in the southern coast of South Africa , provided evidence that marine resources shellfish have been regularly exploited by humans as of , years ago. Archaeologists are seeking an accurate dating technique, but this method is yet to be found. Tephrochronology Group 'The correlation and geochemical analysis of volcanic ash deposits tephra allows the identification and dating of isochronous marker horizons within sediment sequences. Finally, absolute dating is obtained by synchronizing the average sequences with series of live and thus datable trees and thus anchors the tree-ring chronology in time. These present many characteristics that are used for comparing them, such as morphology and raw materials in the case of stone tools, and decorative techniques and motifs in the case of ceramics. Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology. Tephrochronology thus provides a precise and well-established dating tool, already widely used in the study of Quaternary environmental stratigraphies. These sequences are then matched one against another by the dendrochronologist and compared with growth sequences whose dates are known from living trees.

    Relative Dating Stratigraphy Inspired by geology , stratigraphy uses the principle of the superposition of strata which suggests that, in a succession of undisturbed SOILS , the upper horizons are newer than the lower ones.

    Sometimes researchers can determine a rough age for a fossil based on established ages of other fauna from the same layer — especially microfauna, which evolve faster, creating shorter spans in the fossil record for each species.

    Certain unstable isotopes of trace radioactive elements in both organic and inorganic materials decay into stable isotopes. These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well.
