September 30, by. Dinosaurs disappeared about 65 million years ago. That corn cob found in an ancient Native American fire pit is 1, years old. How do scientists actually know these ages? Geologic age dating—assigning an age to materials—is an entire discipline of its own.
Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings dendrochronology and varve analysis. Since the physical sciences contributed a number of absolute dating techniques that have had a revolutionary effect on archaeology and geology. These techniques are based upon the measurement of radioactive processes radiocarbon; potassium-argon, uranium-lead, uranium-thorium, thorium-lead, etc. Other techniques are occasionally useful, for example, historical or iconographic references to datable astronomical events such as solar eclipses archaeoastronomy.
