Uncalibrated radiocarbon measurements are usually reported in years BP where 0 (zero) BP is defined as AD 1950.
BP stands for “Before Present” or “Before Physics” as some would refer to it.
Abstract: The discovery of collagen in a Tyrannosaurus-rex dinosaur femur bone was recently reported in the journal Science.
The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.
I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods.
See those previous posts for the background of my theory.
