date of organic material - but an approximate age, usually within a range of a few years either way.
The other method is “Relative Dating” which gives an order of events without giving an exact age (1): typically artefact typology or the study of the sequence of the evolution of fossils.
Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.
Raw (i.e., uncalibrated) radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), with "present" defined as CE 1950.
Such raw ages can be calibrated to give calendar dates.
University of Utah geochemists developed a new way to fight poaching of elephants, hippos, rhinos and other animals.
Carbon-14 from 1950s and 1960s nuclear weapons tests was and still is deposited in animals' tusks or teeth, and those carbon-14 levels reveal the year an animal died, and thus whether the ivory was taken before or after international bans on ivory trading. University of Utah researchers developed a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife.
