adele-gQuote:At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method. The age they came back with was only a few thousand years old.
This is an urban legend because at ORNL, the GCMS is set up to do environmental, not archeological dating analyses. Dating requires that the sample be compared to a standard , and, where would we get a standard for the range of accuracy that a dinosaur represents. C14 is accurate down to about 1 pico curies worth of decay. That would make its known range equivalent to about 45K years. Any fool knows that this would be a silly exercise. I can only think of a Creationist even attempting this, even though they would know better
We dont know of any dinosaurs that have carbonaceous fossil remains. Most all are silicified and a very few are of a substance called flouroapatite (a phosphatic compound) The presence of associated carbonates like siderite, calcite etc are only in small associations mostly impossible to sample in context (all these associated carbonates are post diagenetic features and anyone who would sample a calcite vein in a fossil, wouldnt be a candidate for a PEnrose Award, but would be a candidate for the "dummy award"). Im dubious about any story that purports to represent some dumass testing done by a NAtional Lab when everyone I know at ORNL certainly knows better. There are a very few of the Nat Lab guys (like Russ Humphries at Sandia) who profess Creationist views, but they usually keep their mouths shut when actual discussions of data ensue. Just because you see something on the web doesnt make it so.
As far as the "Manmade" suboceanic features that you described, they are, alas, natural and not manmade. They are fractured suboceanic deposits of ancient plutons. These types of rock emplacements always fracture at right angles to the "country rock". Its quite common to see orthogonal or "columnar" fractures in rocks that eroded out of batholiths. The way that this one came to the publics eye was that someone , once saw these features underwater and , without any further analyses, concluded that they were "manmade".Subsequent analyses have shown that there are crosscutting fractures and veins that fit regional tectonic features quite nicely, and that the fractures arent quite 90 degrees but , by using stereographic projections (common tool in structural analyses) the fractures fit the same features located miles away. The features are eroded fracture planes.
