Past events cannot be repeated as per scientific methodology.
For example, try to repeat Abe Lincoln’s life—no one can do it.
These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.
Furthermore, if a sample has been contaminated, scientists will know about it.
Antonio Simonetti, a research associate professor in the Department of Civil Engineering and Geological Sciences at the University of Notre Dame, is the coauthor of an important new paper describing a novel method for age dating dinosaur fossils.
Simonetti and colleagues from the University of Alberta used a U-Pb (uranium-lead) dating technique to analyze a fossilized dinosaur bone discovered in New Mexico.
Perhaps I am not familiar with the passage that clearly describes man walking amongst dinosaurs.
Matt USA About 6,000 years old if you add up the ages given in the genealogies in the Bible from Adam to Christ and factor in certain other timeframes given in the Bible (and of course, add in the five days prior to Adam (since he was made on Day 6)). Trying to determine the age of something gets into what we call “historical” science.
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. Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.Carbon-14 has a half-life of about 5730 years, and therefore it is used to date biological samples up to about 60,000 years in the past.The current method paleontologists use to date dinosaur fossils is a technique called relative chronology.The method estimates a fossils age relative to the known age of deposits of sediment in which it was found. Also, in the bible there is no reference to dinosaurs.
