Document Summary
Time and archaeological record: neanderthals and early modern humans probably didn"t mate in. Context: relation of time and space in a site. Space: not just a final frontier, a critical component of context on multiple scales. Time: all people, from the earliest hominids on, must have been aware of time. Clear evidence for precise time measurement is a recent occurrence. The deeper in the ground, the older it is. Seriation: starts out rare, becomes common, phases out and becomes less popular. Cross dating: going from site to site putting in relative time of what is older/newer. References to geological events, example: maine used to be a glacier 40,000+ years ago. Absolute (chronometric) time: putting a number on something, even if its set up as 2000 bce. Thermoluminescence: heated up pottery, impurities are showed and it becomes evident when the object was created. Potassium-argon dating: potassium decays into argon over time so the ratio is used to measure time.
