How accurate are carbon-dating methods? All methods of radioactive dating rely on three assumptions that may not necessarily be true: Rate of Decay It is assumed that the rate of decay has remained constant over time. This assumption is backed by numerous scientific studies and is relatively sound. However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements. Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant. Thus radioactive dating relies purely on assumptions. We could put forward the following counter arguments to the constancy of these assumptions: The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the carbon to carbon ratio. Pre-Flood dates would thus have to be discarded.
Dinosaurs Had Dandruff Problems, Too
All the original stuff that made it up is gone, and has been replaced by other minerals that merely hold the shape of what was fossilised. You can’t use carbon dating to determine how old the fossil is because there’s fuckall carbon in it to date. Not to mention that Carbon ‘s half-life isn’t exactly huge. Anything older than 45, old is basically not worth Carbon dating at all. That’s as accurate as we can get it.

Definition Triceratops skeleton, Natural History Museum of Los Angeles County Under phylogenetic nomenclature , dinosaurs are usually defined as the group consisting of Triceratops , Neornithes , their most recent common ancestor MRCA , and all descendants. In traditional taxonomy, birds were considered a separate class that had evolved from dinosaurs, a distinct superorder. However, a majority of contemporary paleontologists concerned with dinosaurs reject the traditional style of classification in favor of phylogenetic taxonomy; this approach requires that, for a group to be natural, all descendants of members of the group must be included in the group as well.
Birds are thus considered to be dinosaurs and dinosaurs are, therefore, not extinct. Birds are classified as belonging to the subgroup Maniraptora , which are coelurosaurs , which are theropods, which are saurischians , which are dinosaurs. Norman, and Paul M. Barrett in suggested a radical revision of dinosaurian systematics.
Phylogenetic analysis by Baron et al. They resurrected the clade Ornithoscelida to refer to the group containing Ornithischia and Theropoda. Dinosauria itself was re-defined as the last common ancestor of Triceratops horridus , Passer domesticus , Diplodocus carnegii , and all of its descendants, to ensure that sauropods and kin remain included as dinosaurs.
Using one of the above definitions, dinosaurs can be generally described as archosaurs with hind limbs held erect beneath the body.
Carbon-14 in Coal Deposits
Welcome to the home of The Question Evolution Project. Presenting information demonstrating that there is no truth in minerals-to-man evolution, and presenting evidence for special creation. Others tried to downplay and ignore them, but they’re here — and they’re spoiling Darwin’s party. It shouldn’t be a surprise to learn that Darwin’s disciples are loathe to have dinosaur fossil tissue tested for carbon

Here, RSR presents the scientific journals reporting, the kinds of biological material found so far, and the dinosaurs yielding up these exciting discoveries: Dinosaur and Dinosaur-Layer Creatures: As you view the exciting scientific discoveries below in this chronological catalog, please feel free to listen to Real Science Radio co-hosts Fred Williams and Bob Enyart observe their annual tradition of presenting dinosaur soft tissue and other amazing discoveries including short-lived left-handed amino acids , DNA , and Carbon 14 , all in bones and other specimens from dinosaur-layer Mesozoic and even deeper strata.
As for these photos though, North Carolina State University discovered this original biological tissue from a supposedly million-year-old Tyrannosaurus Rex thighbone, with transparent and pliable blood vessels containing red blood cells. See these and other T. In a development, ten leading universities and institutes including Harvard, the University of Manchester, and the University of Pennsylvania published in PLoS One, a peer-reviewed journal, that they had verified that presumed dinosaur material is indeed original biological tissue from a dinosaur!
Creationists refer to dinosaurs as missionary lizards for many reasons including: Interestingly, the renowned evolutionist PZ Myers ridiculed our Real Science Radio program by repeating what had been a widely-discredited secular hope that the “soft-tissue” dinosaur finds were ” biofilm ” contamination from bacteria. But as 60 Minutes shows and Bob Enyart sums it up, “This is dinosaur.
Radiometric Dating of Recent Dinosaur Bones — Censored
The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods , at some age which is a lot below the ‘usual’ i. The age that these groups claim to find is usually on the order of thousands or tens of thousands of years old.
The particular example you bring up is one of the most famous such cases. The claims are really quite spectacular, when taken at face value, and therefore should be examined thoroughly. In this answer, I will try to go through this story in great detail, hopefully exposing the reasons why this work is not taken seriously by scientists.
If dinosaurs really did die out millions of years ago, they could not be dated using carbon 14 dating because all the carbon 14 that was in their bodies would have decayed in 50, years or less. Therefore, despite what Lewis Black says, carbon 14 dating can’t prove fossils are millions of years old.
The Oldest Living Thing: The oldest living thing on earth is either an Irish Oak or a Bristlecone pine. If we assume a growth rate of one tree ring per year, then the oldest trees are between 4, and 4, years old. Also, with regard to fossil tree rings, the author has been unable to find any documented instances of fossil trees having more than about rings. This is significant since we are told that God literally made the Earth, and all that is in it, only about years before the Noachian Flood described in the Book of Genesis.
In a Bristlecone Pine tree was discovered that has just over 5, tree rings. Helium in the Atmosphere: Helium is a byproduct of the radioactive decay of uranium as it decays into various different elements into its final stable element:
1. Rate of Decay
Very precise analysis from modern mass spectrometers can establish the date the living material in the sample stopped taking in carbon from the environment the point of death. Because C has such a short half-life radioactively decaying into Nitrogen 14 , all detectable C should have disappeared well before , years. But careful analysis by researchers has substantiated the presence of Carbon 14 in dinosaur bones.
Critics suggested that the samples became contaminated with modern Carbon
Dino Soft Tissue Confirms Creationist Prediction Sooner or later, someone will do a carbon test on dinosaur soft tissue. If there is any C found at all, it will defeat the geologic column with its “Age of dinosaurs” ending millions of years ago. When radiocarbon dating any fossil bone, not just dinosaur bones, it is usually.
Many Christians today believe as an article of faith that the Bible teaches the earth was created 6, years ago. They dispute all the evidence of geology, paleontology and radiometric dating techniques. They argue that such evidence is invalid, grossly misunderstood, and misinterpreted. Some Neo-Creationists claim that all the earth’s strata was due to the Noachian deluge, or the original process of Creation.
They claim all Creation took place during a six day period approximately 6, years ago. What is the truth? However, the Bible nowhere says Creation occurred 6, years ago. Nor does it teach that the earth is flat, although Medieval theologians often assumed so and threatened anyone who would teach otherwise with excommunication and torture.
The Middle Ages were a sad time in theological history. The supposedly enlightened Church pressured scientists such as Bruno and Galileo with the threat of bodily harm if they chose to believe the earth revolved around the sun. Irrational Theology Catholic theologians made a great mistake in the Middle Ages. They assumed the Scriptures taught things about the material universe which were, in fact, false interpretations or assumptions.
Age of the earth
A creationist source that makes an argument about anomalous 14C in coal deposits. Accelerator mass spectrometry AMS , a sensitive radiometric dating technique, is in some cases finding trace amounts of radioactive carbon in coal deposits, amounts that seem to indicate an age of around 40, years. Though this result is still too old to fit into any young-earth creationist chronology, it would also seem to represent a problem for the established geologic timescale, as conventional thought holds that coal deposits were largely if not entirely formed during the Carboniferous period approximately million years ago.
Since the halflife of carbon is 5, years, any that was present in the coal at the time of formation should have long since decayed to stable daughter products. The presence of 14C in coal therefore is an anomaly that requires explanation.

Senior research scientist Alexander Cherkinsky specializes in the preparation of samples for Carbon testing. He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports. Carbon dating at this facility is certainly the very best. But in , someone told the director of the facility, Jeff Speakman, that the Paleochronology group was showing the Carbon reports on a website and YouTube and drawing the obvious conclusions.
So when he received another bone sample from the Paleochronology group, he returned it to sender and sent an email saying: The scientists at CAIS and I are dismayed by the claims that you and your team have made with respect to the age of the Earth and the validity of biological evolution. Consequently, we are no longer able to provide radiocarbon services in support of your anti-scientific agenda. I have instructed the Radiocarbon Laboratory to return your recent samples to you and to not accept any future samples for analysis.
