Another Bone to Pick

For the past two decades, paleontologist Mary Schweitzer has been at the cutting edge of research demonstrating that certain dinosaur remains contain original soft tissue. Of course, since this material should have completely decomposed after only thousands of years, none should be left after the millions of years assigned to these remains. And this is why scientists who have chosen to investigate soft tissue remain divided over the issue. Schweitzer’s latest technical report attempts to justify that in-bone collagen recovered from dinosaur remains is original to the dinosaur—and not a bacterial or lab-bench contaminant—on the basis of the peculiarities of the collagen protein’s three-dimensional structure. Collagen is a tough structural protein that bacteria do not manufacture. It forms long strands and acts like molecular strings that tie or connect other tissues such as skin and bones.

Denial of Facts in Science

Let me see if I can put this together: Dinosaurs died out about 65 million years ago, yes? And it takes a long, long time for bones and things to turn into fossils, yes? So, in the huge amount of time required to turn bones into rock, other stuff must have rotted or fallen off, yes? Never mind that something soft can be exposed to the proper elements and conditions and become petrified . Here is another example of how philosophers of science will tap dance around the facts against evolution and still cling to their faith. Seems to me that it's not possible to find a Tyrannosaurus Rex bone with soft tissue still attached. But it happened. It shouldn't have happened. But it did. This article ignores the facts and scientists still manage to get excited: "To my knowledge, preservation to this extent—where you still have original flexibility and transparency—has not been noted in dinosaurs before, so we're pretty excited by the find," said Mary H. Schweitzer, a
