That causes a dating problem with any animal that eats seafood. After about ten half-lives, there's very little C14 left.
Indeed both bones contained collagen and conventional dates of 30,890 ± 380 radiocarbon years (RC) for the Triceratops and 23,170 ±170 RC years for the Hadrosaur were obtained using the Accelerated Mass Spectrometer (AMS).
It is also standard to coat fossils during their extraction and transport.
Acetone is sometimes used while extracting fossils, because it dissolves dirt.
This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. The short half-life of carbon-14 means its cannot be used to date extremely old fossils.
Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharohs among other things. Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 remains undecayed).
Accelerated Mass Spectrometer (AMS) dating of dinosaur bone bio-apatite from 170 grams of bone fragments and milligram surface scrapings of an Acrocanthosaurus dinosaur gave ages of 25,750 ± 280 and 23,760 ± 270 respectively.
No collagen was detected and only bone bio-apatite was RC dated.
He believes this can be done by measuring the carbon isotope C13.
For a long time radiocarbon dating has been widely considered the best method for determining the age of organic materials.
It is produced in the upper atmosphere by radiation from the sun.
(Specifically, neutrons hit nitrogen-14 atoms and transmute them to carbon.) Land plants, such as trees, get their carbon from carbon dioxide in the air. The same is true of any creature that gets its carbon by eating such plants. Suppose such a creature dies, and the body is preserved.
Human carbon dioxide emissions have sped up the reduction of the carbon isotope 14C in the Earth’s atmosphere, bringing into question the accuracy of the method’s results.
