and it’s not being replaced in the standard modern diet.As your body slows its collagen production, you’ll typically end up with skin that “looks older” with less skin elasticity, vibrancy and hydration, creaky joints, or even gut disturbances. The typical woman can expect to lose about 1 to 2 percent of her body’s collagen every year starting in her mid-30s, and this rate generally only increases as she makes her way through her 40s, 50s and beyond.Internet Explorer (IE) is no longer supported (version 10 and down).Please upgrade your browser to improve your experience.The data was challenged by Thomas Stafford as poor science due to assumed contamination from modern C-14 with younger surficial calcium carbonate.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.Bone samples were characterized for collagen quality using well-established elemental abundance analyses (i.e., percentage nitrogen and C: N) as the primary criteria for classification.FT-Raman spectra were collected from outer surfaces and freshly cut cross-sections of both well-preserved and poorly-preserved historic mammal bones.
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.
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).
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.

Abstract This study examines Fourier transform (FT) Raman spectroscopy as a non-destructive screening method to determine collagen quality in archaeological and paleontological bones.
