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.

There’s a reason that collagen supplementation, in addition to an overall healthy diet and lifestyle, is being dubbed as the new essential in the wellness and beauty community.

Many people’s collagen is breaking down at an accelerated rate…

FT-Raman spectra from bones with well-preserved collagen produced a 960 cm-36 cm-1 ratio of 19.4 or less (after peaks were baseline corrected).

This mineral to collagen ratio was typically greater in poorly-preserved samples as organic material tends to be more susceptible to early stages of diagenesis.

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

These criteria now can be used to accurately determine collagen quality in bones before sacrificing samples to the lengthy and destructive chemical extractions necessary for carbon-14 dating, stable isotope analyses, proteomic analyses, and other techniques of archaeological or paleontological interest.

Abstract: The discovery of collagen in a Tyrannosaurus-rex dinosaur femur bone was recently reported in the journal Science.

But frankly, even the healthiest diets are quite low in collagen, because only a small number of foods have a significant amount of it.

All of the above are great collagen boosters, but none of them compare to the greatest collagen booster in the world, which is collagen itself that comes from sources including chicken broth, beef broth, wild fish broth and eggshell membranes.A ratio of the 960 cm- cm-1 peak heights provided the most unambiguous distinction between bones with well-preserved and poorly-preserved collagen.
