Can carbon dating be used on dinosaur bones puzzle


Why is there Carbon 14 in Dinosaur bones?

Is it possible that it is background Carbon 14, or is it a contaminate? This article deals in depth with claims of certain creationist researchers that C14 was found in dinosaur bones. Good article, which points out the sad negative effect that such willful misrepresention has on the gospel message. Also, just to be clear, there are no dinosaur bones, only dinosaur fossils, where the original biological carbon has been replaced by minerals, except perhaps in rare cases where trace amounts of collagen may persist.

Carbon may also be present through contamination, and through naturally occurring biofilms.

Also, at the lower limits of detection, I understand that residual carbon in the testing equipment makes for noise which limits dating. Much has been said, but remember that the organic residual is tiny, and some of what people refer to as soft tissue, is mineralized structures in the shape of soft tissue: I am sure interesting developments are yet to come.

Here is a helpful article: Incidentally, while I was looking for your first link I found this one from back in I thought it did a good job presenting what Schweitzer saw her research as and how it was co-opted by other groups.

Regarding soft tissues, I came upon this blog that is a great overview. Lots other I interesting articles also: He must have taken Every One of those Animals alive on the Earth … because they do not share the fossil record with all of the Flood victims! The work by Mary Schweitzer and her colleagues has shown that at least some of the flexible tissues from deep within the dinosaur bones she examined is original organic material, not merely recent biofilm.

In particular, it is implausible...

However, these tissues have been significantly stabilized by cross-linking in the course of aging. While there is evidence for some heme units heme is a stable portion of hemoglobinthere are no actual red blood cells.

For other fossil dinosaur samples, it is possible that the flexible material found in them is recent bacterial biofilm, not original organic molecules. Thomas Kaye presented convincing evidence that some of the flexible material he extracted from fossil dinosaur or turtle remains was biofilm. He also found that little red objects which initially looked like red blood cells in blood vessels were actually microclusters of iron oxide.

That scientists are unable at present to give a complete account of the mechanism and trajectory of the preservation of modified proteins in the dinosaur bone pores is not some unique, embarrassing case.

This situation arises constantly in the course of scientific discovery. But when genuine science is brought to bear on these issues, they are eventually readily explained within the framework of an old earth and accepted physics.

What exactly are we dating...

It may take some years, however, to come to a satisfactory resolution. A number of these supposed evidences for a young earth are exposed here. The absence of long, sequenceable chains of DNA in any dinosaur fossils indicates that these fossils are much older than the year age allowable in young earth creationism.

The same held true for sequences of proteins.

Christy Christy Hemphill Im so confused about that. Excellent material at that link… It just inspired me to create a new thread: The Great Ark Fossil Mystery!!! Where are the bones of Any of the species, pairs of which Noah brought on board the Ark?
