A couple of questions.
1. Is 'highly fibrous, flexible, and elastic bone tissue that when stretched, returns to its original shape' and accurate description of what was really found?
2. If it's not, why are there conclusions being drawn based on the premise that it was?
UUhhmmmm....?
to answer both questions,
The material was not “expected” to remain flexible.
It was not fossilized.
It raises questions about age.
we know that fossilization does NOT take long. it begs the question, How long did it take, how old is this fossil.
Now to question standing evolutionary thought, is un thinkable!
Honestly is needed.
So tactic, are you just trying to sow doubts about stuff that ‘s been reported for almost 10 years now?
“In the course of testing a B. rex bone fragment further, Schweitzer asked her lab technician, Jennifer Wittmeyer, to put it in weak acid, which slowly dissolves bone, including fossilized bonebut not soft tissues. One Friday night in January 2004, Wittmeyer was in the lab as usual. She took out a fossil chip that had been in the acid for three days and put it under the microscope to take a picture. [The chip] was curved so much, I couldnt get it in focus, Wittmeyer recalls. She used forceps to flatten it. My forceps kind of sunk into it, made a little indentation and it curled back up. I was like, stop it! Finally, through her irritation, she realized what she had: a fragment of dinosaur soft tissue left behind when the mineral bone around it had dissolved. Suddenly Schweitzer and Wittmeyer were dealing with something no one else had ever seen. For a couple of weeks, Wittmeyer said, it was like Christmas every day.
In the lab, Wittmeyer now takes out a dish with six compartments, each holding a little brown dab of tissue in clear liquid, and puts it under the microscope lens. Inside each specimen is a fine network of almost-clear branching vesselsthe tissue of a female Tyrannosaurus rex that strode through the forests 68 million years ago, preparing to lay eggs. Close up, the blood vessels from that T. rex and her ostrich cousins look remarkably alike. Inside the dinosaur vessels are things Schweitzer diplomatically calls round microstructures in the journal article, out of an abundance of scientific caution, but they are red and round, and she and other scientists suspect that they are red blood cells.
