Radioactive carbon 14 dating dinosaur, dinosaur soft tissue and other organic material found

For amounts in between, an exponential formula is used to relate the percentage of remaining C with the age. The video is at https: This is a remarkable find because collagen, being a soft tissue present in most animals, is supposed to decay in a few thousand years.

I should also point out, that we were so concerned about the extraordinarily ancient dates of these figures, that Mark Han in our lab made an average of 18 runs on each one of the four samples.

It is fairly accurate and can go to a few tens of thousands of years back in time. It is about a commilitones latino dating tall.

Praise for Armitage's work continued from distinguished members of the Biology Department. Typically, the object must be less than 50, or so years old.

They all start with similar flaws, but Carbon has more than the rest. The few centimeters of motion in the plates measured now is due to a difference in how fast the outer lithosphere rotates versus the inner mantle, a mechanism proposed for Plate Tectonis by mainstream geologists years ago.

The results of C14 dating a very old sample with no C14 left is unpredictable, and anyone who doesn't understand this doesn't understand how the process works. Animals take up atmospheric 14C indirectly, by eating plants or by eating other animals that eat plants.

The ramifications of this information are stunning. These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.

Yet the footprints are supposedly 3 million years old. What can carbon dating be used to measure? I posted comments that he at first answered and then removed when he saw they demolished his position.

This discovery brought world wide attention from archaeologists who at first mistakenly defined them as Tarascan, but later they were correctly identified as a whole New Indian culture - the Chupicuaro. As stone and wood are being re-used from previous buildings to construct new buildings, the carbon in the wood will be elevated in the strata.

There are gross discrepancies, the chronology is uneven and relative, and the accepted dates are actually selected dates. How Carbon has been used to date dinosaur bones to between 22, and 39, years before present.

Creation Worldview Ministries: Carbon Dating Technique Does Not Work!

Armitage reported this to the Biology Department chair, Dr. This is not the scientific way, ignoring new information because it does not fit your present ideas!! This process might occur more than once for a specific piece of wood.

Though it is not without its flaws, including several not mentioned here, it is truly an incredible creation that will be used for many years to come. Commentary Radiocarbon RC or Carbon C dating of linen, cotton, bones, fossils, wood, sea shells, seeds, coal, diamond anything with carbon is one of the most common and well understood of the various scientific dating methods.

Therefore, there would have to be thousands of times more uranium, thorium, etc. When wood, fabrics, leather, human bones and teeth are carbon-dated, we already have a multitude of independent evidence that gives us some idea of about how old these items are.

Considering Contamination

If this water vapor did exist in the past, then it would have effectively shielded the atmosphere from much of the cosmic radiation. Consequently, we are no longer able to provide radiocarbon services in support of your anti-scientific agenda.

Sedimentology lab and flume studies as also published in book, Evolution: Implications for population development and late quaternary environment," Radiocarbon 39 1 pp.

Second, there is the assumption that the formation of Carbon has been constant throughout the years. Therefore, it is labeled a short term radiometric dating technique. Some of this carbon is carbon, and it is radioactive - it decays over time.

How accurate are Carbon and other radioactive dating methods? Several hundred of the figurines were scientifically identified as representing many species of dinosaurs, including duck billed Trachodon, Gorgosaurus, horned Monoclonius, Ornitholestes, Titanosaurus, Triceratops, Stegosaurus Paleococincus, Diplodocus, Podokosaurus, Struthiomimos, Plesiosaur, Maiasaura, Rhamphorynchus, Iguanodon, Brachiosaurus, Pteranodon, Dimetrodon, Ichtyornis, Tyrannosaurus Rex, Rhynococephalia and other unknown or as yet unidentified dinosaur species.

There should be no measurable Radioactive Carbon in this tree! As a result of decomposition, to the extent that original carbon atoms were falling out of the tissue so to speakthen to that extent you would no longer have collagen; rather, to that extent you would have humic acid.

This attempt to calibrate Carbon utterly fails for two reasons.

In like manner, there is really no such thing as a closed system in nature. The research by Miller et al.

Different statistical models are used by different researchers.

Places that it should not exist at all. Julsrud, who was archaeologically astute, immediately realized that these ceramic pieces were unlike anything that he had seen. The other more reasonable explanation is that these bones are not million years old and that the method used to determine that million year age is flawed.

In the traditional approach the scientist is actually measuring the levels of beta activity from a sample. In addition, the initiation of atomic bomb testing on July 16,and the subsequent above ground testing between andcaused a rise in neutrons which in turn increased Carbon concentrations around the world.

Thus one can now examine a footprint and see if the density of the hardened material changes along the footprint area. Carbon is the parent isotope, its constant decay rate is about years.
