Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.

When it comes to dating archaeological samples, several timescale problems arise.

But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.

It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.

Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.

Chronometric techniques include radiometric dating and radio-carbon dating, which both determine the age of materials through the decay of their radioactive elements; dendrochronology, which dates events and environmental conditions by studying tree growth rings; fluorine testing, which dates bones by calculating their fluorine content; pollen analysis, which identifies the number and type of pollen in a sample to place it in the correct historical period; and thermoluminescence, which dates ceramic materials by measuring their stored energy.

Scientists first developed absolute dating techniques at the end of the 19th century.

Historians can tell what cultures thrived in different regions and when they disintegrated.

Anthropologists can describe a people’s physical character, culture, and environmental and social relations.
