Carbon dating dinosaur soft tissue
"If you could dissolve the bucket away, you'd find soft, squishy material in the shape of the bucket, and that's the slime," Kaye said. If you dissolve away the bone, what's left is biofilm in the shape of vascular canals." Co-authors of the new paper are Gary Gaugler of Microtechnics Inc.
of Granite Bay, Calif., and Zbigniew Sawlowicz of Jagiellonian University in Poland.
He likens the phenomenon to what would happen if you left a pail of rainwater sitting in your backyard.
After a couple of weeks you would be able to feel the slime that had formed on the inner walls of the bucket.
But new research challenges that finding and suggests that the supposed recovered dinosaur tissue is in reality biofilm – or slime.
"I believed that preserved soft tissues had been found, but I had to change my opinion," said Thomas Kaye, an associate researcher at the Burke Museum of Natural History and Culture at the University of Washington.
Kaye said he began his research with the hope of being the second person to find preserved dinosaur tissues.

What they have been telling us simply does not fit the facts.
The truth is that this latest find is even more evidence that dinosaurs are far, far younger than we have traditionally been taught.
In addition, they examined what looked like tiny cracks within the vascular canals and found that they were actually small troughs, or channels.
Study at high magnification revealed the channels had rounded bottoms and bridged each other, indicating they were organically created, likely by bacteria moving in a very thick solution.
