Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old.To determine the ages of these specimens, scientists need an isotope with a very long half-life.This has been argued before, but the testing process itself is loaded with procedures that rigorously remove contaminants.Secular researchers routinely detect radiocarbon in carbon-containing materials like coal, oil, marble, and diamond—materials they would like to use as "carbon dead" standards.Comparable amounts of radiocarbon showed up in almost 50 total samples.Defenders of evolutionary time scales will have to assert that the radiocarbon all came from some sort of contamination, where recent or modern carbon somehow crept into all these samples.The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years.If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them.

Key Words: Radiocarbon dating, dinosaur, bone collagen, organic carbon, bone bio-apatite, fossil wood, amber, megafauna Introduction Bone collagen and soft tissue were recently reported as having been discovered in a Tyrannosaurus dinosaur femur bone as well as other fossil bones from the Cretaceous period of the geologic column by Mary H. The RC ages for extracted bone collagen for Smilodon femurs ranged from 12,650 ±160 to 28,000 ±1400 RC years BP (Before the Present). Libby, the inventor of the radiocarbon dating method, "There is no known natural mechanism by which collagen may be altered to yield a false age." It is common practice to determine the age of bones by radiocarbon (RC) dating of extracted bone collagen but not of dinosaurs because they are assumed to have become extinct 65 million years BP and, therefore, too old for RC dating.The preferred method of dating dinosaur fossils is with the radiometric dating method.And the result of this accepted method dates dinosaur fossils to around 68 million years old. Its half-life ($t_$) is only 5,730 years—that is, every 5,730 years, half of it decays away.The CRSQ study authors tested seven dinosaur bones, including a from Montana, hadrosaurids, a cartilaginous paddlefish, a bony fish, and fresh-looking wood and lizard bones from Permian layers in Canada and Oklahoma.Five different commercial and academic laboratories detected carbon-14 in all the samples, whether from Cenozoic, Mesozoic, or Paleozoic source rocks. The team also compared the results to several dozen published carbon-14 results for fossils, wood, and coal from all over the world and throughout the geologic column.
