lexicostatic dating and glottochronology This is a technique used to estimate the age of languages and the dates of divergence between two languages. Dating techniques are procedures used by scientists to determine the age of an object or a series of events.Some fossils, called index fossils, are particularly useful in correlating rocks.For a fossil to be a good index fossil, it needs to have lived during one specific time period, be easy to identify and have been abundant and found in many places. If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic.But some of the techniques are similar in principle.

This margin for error can be reduced by corroborating with other dating methods like dendrochronology.While human cultural remains are rarely found in these layers, sites of human habitation can be relatively dated by comparing associated pollen and diatoms.This is a useful tool in corroborating other methods of dating. Throughout the history of life, different organisms have appeared, flourished and become extinct.Many of these organisms have left their remains as fossils in sedimentary rocks.
