- Can We Use Carbon 14 Dating On 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Also, just to be clear, there are no dinosaur bones, only dinosaur fossils, where the original biological carbon has been replaced by minerals, except perhaps in rare cases where trace amounts of collagen may persist.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.

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 hemoglobin , there 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. By using radiometric dating to determine the age of igneous brackets , researchers can accurately determine the age of the sedimentary layers between them.

Using the basic ideas of bracketing and radiometric dating, researchers have determined the age of rock layers all over the world. This information has also helped determine the age of the Earth itself. While the oldest known rocks on Earth are about 3. Based on the analysis of these samples, scientists estimate that the Earth itself is about 4.
In addition, the oldest known moon rocks are 4.tiokingfastbi.tk

Since the moon and the Earth probably formed at the same time, this supports the current idea of the Earth's age. You can learn more about fossils, dinosaurs, radiometric dating and related topics by reading through the links below. Radiometric dating isn't the only method of determining the age of rocks. Other techniques include analyzing amino acids and measuring changes in an object's magnetic field.

Scientists have also made improvements to the standard radiometric measurements. For example, by using a laser, researchers can measure parent and daughter atoms in extremely small amounts of matter, making it possible to determine the age of very small samples [source: Saber-tooth Kittens Were Big-boned.
