"We may not really know as much about how fossils are preserved as we think," says Schweitzer. "Our preliminary research shows that antibodies that recognize collagen react to chemical extracts of this fossil bone. If further studies confirm this, we may have the potential to learn more not only about the dinosaurs themselves, but also about how and why they were preserved in the first place."
It doesn't change the age of the fossil, just a question of the process itself.

Well, naturally we wouldn't want to let any facts challenge accepted theory.
Poppycock. A number of theories are being reevaluated in light of Schweitzer's discoveries. That is what real science is about, it is how and why it works. Incidentally, Schweitzer did not claim to have found "dinosaur blood vesels", but rather to have discovered evidence of something not inconsistent with a type of vascular tissue today peculiar to ovulating birds, and something not inconsistent with hemeglobin-bearing cells. Here's an article discussing that, as well as shedding a bit more light on the find itself, the methodology of Schweitzer's research, and its relationship to and confirmation of earlier work.

A teaser:
Quote: ... A pathologist attending her talk pointed out that the sample contained something that looked like red bloodcells. Callis returned the sample to Schweitzer, who peered at it through her microscope with amixture of heart-stopping wonder and complete disbelief. Horner was summoned; he askedSchweitzer if she thought she really had foundpreserved dinosaur blood cells. "No," she told him.
"Fine," he said. "Then prove that they're not." ...
And now for a touch of comic relief -
Here's the official ID-iot take, straight from The Discovery Institute:
Quote:The Devastating Issue of Dinosaur Issue
Abstract
Although it is too early to make definite statements regarding this stunning and wholly unexpected find, the evidence seems to indicate the T. rex fossil is--??well,
young.
Yup, the head whackos at the Discovery Institute are thilled; this proves to their satisfaction dinosaurs didn't live scores of millions of years ago.
