So, when you see 2000 cal BP, think "2000 years before the calendar year 1950" or what calculates to the calendar year 50 BCE.No matter when that date is published, it will always mean that.The carbon-14 method was developed by the American physicist Willard F. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.Scholars now typically cite both raw, uncalibrated radiocarbon dates as years RCYBP (radiocarbon years before the present as 1950), alongside calibrated versions of those dates as cal BP, cal AD and cal BC (calibrated or calendar years BP, AD, and BC).That probably seems excessive, but it will always be useful to have a stable starting point in the past to hook our dates on, despite the outmoded religious underpinnings of our modern, multiculturally-shared calendar.Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.

If it was a simple matter of counting backward, what was accurately measured and published as 500 BP today in fifty years would be 550 BP.Nonetheless, 1950 is a long time ago now—should we adjust the starting point to 2000?
