Re: Dino Blood In Video
Thanks, that's great!

Putting this information into the context of the discussion, creationists cite the presence of blood in dinosaur bones as evidence of young age because it seems impossible for blood to be preserved for millions and millions and years, and up until recently paleontologists would have agreed.

But evidence is evidence, and paleontologists were forced to change their minds. It now appears that under special conditions, such as fossils encased in clay rich rock that protects them from mineralization, at least some soft tissue structures can survive for extremely long periods of time.

Summarizing more completely, all the evidence says that the last dinosaurs died about 65 million years ago (excluding birds), and that their fossil remains are found in various states of preservation ranging from poor to excellent. Under the most fortunate of circumstances dinosaur soft tissue structures have been identified.

common young earth creationist (YEC) misinterpretation of the discovery of surviving organic molecules in ancient bone is that this "proves" that the Earth is young and that geological and radiometric data should be ignored. The ancient surviving materials they commonly refer to are fragments of hemoglobin and osteocalcin (a bone protein) extracted from dinosaur bone. There are many problems with their position, but ultimately it reduces to nothing other than they just don't think that organic molecules can last a long while. The "Creation Science" approach is to deny the independent results of geology, chemistry and astronomy because these molecules exist.
