“that’s “rock”, for the homeschooled”
Wow could you be any more condescending?
I don’t know the original source. Would you care to share a link?
“Schweitzer was interested in studying the microstructure and organic components of a dinosaur’s bone. All bone is made up of a combination of protein (and other organic molecules) and minerals. In modern bone, removing the minerals leaves supple, soft organic materials that are much easier to work with in a lab. In contrast, fossilized bone is believed to be completely mineralized, meaning no organics are present. Attempting to dissolve the minerals from a piece of fossilized bone, so the theory goes, would merely dissolve the entire fossil. But the team was surprised by what actually happened when they removed the minerals from the T. rex femur fragment. The removal process left behind stretchy bone matrix material that, when examined microscopically, seemed to show blood vessels, osteocytes, or bone building cells, and other recognizable organic features.”

You are misrepresenting her work. It was demineralized and all the ROCK was dissolved leaving behind what wasn’t rock.
You need a definition of "snidely"?
Gee, you don't know the original source (really not hard to find), yet you're gonna keep on posting words from a REPORTER? Is that how homeschoolers are taught "science"? "Hey kids, forget the actual research....here's a reporter's take on it"...better yet, here's lyin' Brian Thomas MS8 take on it.
You are misrepresenting her work. It was demineralized and all the ROCK was dissolved leaving behind what wasn’t rock.
I misrepresent nothing, and you need an english comprehension class....as that's EXACTLY WHAT I'VE SAID ALL ALONG....in contradistinction to what lyin' Brian Thomas MS* keeps on saying that "soft tissues were found"...that "blood cells were found" in the fossils, leaving YECers to believe they found "soft" "tissue" and actual blood cells, when they've found "fossilized" "soft tissue" and "fossilized" "blood cell structures"...and and the presence of heme and some protein fragments...."soft tissue" is a medical term...I'm sure your dictionary can help you.
The real reason why this is "news" is because she did to the samples what paleontologists don't do...destroy the sample, instead of preserve it at all cost.
From all this....that they were able to demineralize a fossil and find a fibrous matrix....does that tell YOU that T. rex walked the Earth with Man within the last 4,531 years? Tells me that we don't know as much about decay and fossilization in anoxic environments as we thought.
