Soft tissue in a supposedly 70-million-year-old bone? How did that survive?
These are not just stretchy ligaments with identifiable proteins, but flexible transparent branching blood vessels, containing an ooze that could be squeezed out like toothpaste. And inside these vessels were the easily identifiable remains of red blood cells, even showing the nuclei, typical of reptiles .

So long as the 65 to 70 million year is held sacrosanct the scientists will accept a turkey-like T.rex leaving behind blood samples.
Anything other than questioning their time line.

Do you have a ping list for these great nature/science articles you find?
If you do, please add me.

Now, does this mean that timelines for dinosaurs are incorrect, or does it mean the dinosuars existed well past the timeline that was given?
In other words, is it a cosmic joke played by an amused God (God made it all in a past much closer than mankind thinks, with things mankind can look at and speculate that things are much older), or did diosuars exist 60,000,000 years ago AND live well into the age when mankind also roamed the earth.
OR, is it something no one has thought of yet?

VERY neat stuff. I wonder how many other soft tissue remains have been missed by people who KNEW they could not be found?

He told us this all happened about 10,000 years or so ago. He also told us the firmament was separated by water; but "settled science" just "knew" the earth was flat. I don't think it was a cosmic joke that Columbus didn't sail off the edge of the earth either.

The latest evidence comes from a molecular analysis of what look to be bone cells, or osteocytes, from T. rex and Brachylophosaurus canadensis. The researchers isolated the possible osteocytes and subjected them to several tests. When they exposed the cell-like structures to an antibody that targets a protein called PHEX found only in bird osteocytes* (birds are descended from dinosaurs), the structures reacted, as would be expected of dinosaur osteocytes. And when the team subjected the supposed dinosaur cells to other antibodies that target DNA, the antibodies bound to material in small, specific regions inside the apparent cell membrane. So, Young Earth Evolution it is.
LOL.
Actually, the only thing that the article hints at is a scientific proof for evolution.

Funny how the promoters of ignorance ignored that part.

I’m amazed that any kind of organic matter (of living origin) can survive 70 million years. I wonder, has radioisotopic dating been done on the samples?

RE: does this mean that timelines for dinosaurs are incorrect, or does it mean the dinosuars existed well past the timeline that was given?
___________________
It’s really hard to answer that question. All we can do is make educated guesses based on the current evidence.
An obvious question arises from Schweitzers work: is it even remotely plausible that blood vessels, cells, and protein fragments can exist largely intact over 68 million years?
While many consider such long-term preservation of tissue and cells to be very unlikely, the problem is that no human or animal remains are known with certainty to be 68 million years old.
If dinosaurs died off only just thousands years ago (instead of millions as is generally believed), would we expect the preservation of vessels, cells, and complex molecules of the type that Schweitzer reports for biological tissues historically known to be just thousands of years old?
Many studies of Egyptian mummies and other humans of this old age (confirmed by historical evidence) show all the sorts of detail Schweitzer reported in her T. rex. In addition to Egyptian mummies, the Tyrolean iceman, found in the Alps in 1991 and believed to be about 5,000 years old, shows such incredible preservation of DNA and other microscopic detail.
So, I would guess that answering “yes” isn’t really stretching it based on the evidence we’re seeing thus far.
