Total organic carbon and/or dinosaur bone bio-apatite was then extracted and pretreated to remove potential contaminants and concordant radiocarbon dates were obtained, all of which were similar to radiocarbon dates for megafauna. Walter Libby's team of collagen from "dense mid-shaft femur bones" of twelve extinct saber tooth tigers, [Smilodon] from the Le Brea Tar Pits of Los Angeles CA.
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.
Many such lines of evidence (multiplying as at youngearth.com) undermine the claim by old-earth geologists that the plentiful 14c in "ancient" specimens must come from contamination or neutron capture (see below), and this evidence helps to confirm the young earth interpretation of the data below.
* Carbon 14 in Dinosaurs at the American Geophysical Conference in Singapore: On how to date a dinosaur, Real Science Radio's Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the 2012 AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs (from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana). Yet each of these dinosaurs had plenty of radiocarbon (as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see Dinosaur Soft Tissue.com).
With the scientific breakthroughs and discoveries coming in daily, this is a great time to be alive!

Nonetheless, dinosaur bone apatite had been successfully RC dated in the late 1980's/early 1990's and significant amounts of C-14 were detected and reported.
Its geologic location was the Hell Creek Formation in the State of Montana, United States of America.
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.
Even those who initiate the break-up are not immune from this, although the degree of their emotional suffering is different than those who were left behind. If we rush the process of grief we risk leaving some unresolved pain and issues within us that will make an encore appearance in a future relationship.
I was reminded of one of my children’s favorite stories when they were young. Along their way they encountered obstacles like a swampy marsh or dark forest. ” Our healing comes from going through and flowing with our feelings, not bottling them up or denying them. Recently one of my children developed an infection.
