Radio carbon dating stone
Old school radiocarbon dates used to be collected using Geiger counters to establish the amount of radiation they were emitting.
But nowadays, once a sample is successfully collected there are several forms of mass spectrometers and other equipment which can more accurately measure the carbon fourteen level of a sample.
For periods without a historic record, attempts have been made to categorize tool kits, pottery styles, and architectural forms into regional timelines.
Some ill-fated attempts to define time even attempted to count backwards through the genealogies of the Bible, establishing a series of dates which remain a cause of confusion.
And samples must be collected carefully, as often they have been in stable environments prior to their unearthing by industrious archaeologists and may be easily degraded in the open air or attacked by moisture and sunlight once gathered.But other timekeeping methods exist and are still used in the modern world, circumventing the easy processing of dates and history between cultures.Throughout history, time has been defined in a variety of ways: by everything from the current ruler, or empire, or not defined at all.It can date a variety of materials, ranging from, but not necessarily limited to: bone, shell, charcoal, soft tissue, horn, teeth, ivory, hair, blood, wool, silk, leather, paper, parchment, insects, coral, metal if there is charcoal present in it, and sometimes dirt.Carbon dating assumes a variety of things about the natural world in order to work.
