The skull of Daspletosaurus horneri and life reconstruction based on the texture on the facial bones.The face was covered by an extensive mask of large, flat scales, and regions of armor-like skin on the snout, jaws, and ornamental horns.But radiodating cannot proceed without some primary assumptions: the starting conditions of a given sample (e.g., how much of each isotope was present in the beginning), a steady rate of decay of certain radioactive isotopes of elements called radioisotopes, and a lack of tampering with the system (e.g., elements added or subtracted since the radioisotope "clock" first began counting time).
Also, in the bible there is no reference to dinosaurs.
Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.
The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.
You've probably heard scientists talk about things that they claim are millions, if not billions, of years old, though.
A trio of geologists has published what they called the first successful direct dating of dinosaur bone.
Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.
