"Molecular analyses of dinosaur osteocytes support the presence of endogenous molecules.
Schweitzer MH1, Zheng W, Cleland TP, Bern M.
The discovery of soft, transparent microstructures in dinosaur bone consistent in morphology with osteocytes was controversial.
We hypothesize that, if original, these microstructures will have molecular features in common with extant osteocytes.
We present immunological and mass spectrometry evidence for preservation of proteins comprising extant osteocytes (Actin, Tubulin, PHEX, Histone H4) in osteocytes recovered from two non-avian dinosaurs.
Furthermore, antibodies to DNA show localized binding to these microstructures, which also react positively with DNA intercalating stains propidium iodide (PI) and 4',6'-diamidino-2-phenylindole dihydrochloride (DAPI).
Each antibody binds dinosaur cells in patterns similar to extant cells.
These data are the first to support preservation of multiple proteins and to present multiple lines of evidence for material consistent with DNA in dinosaurs, supporting the hypothesis that these structures were part of the once living animals.
We propose mechanisms for preservation of cells and component molecules, and discuss implications for dinosaurian cellular biology."
"Many dinosaur fossils include real bone—they are not completely mineralized, i.e. are not yet ‘rock’.
And what is found inside those dinosaur bones is a huge surprise to many people.
*A series of discoveries since the early 1990s has revealed dino bones with blood cells, hemoglobin, fragile proteins, and soft tissue such as flexible ligaments and blood vessels. And of special note: DNA and radiocarbon. ..
...But so entrenched is the evolutionary paradigm in the scientific community, that it soon became known that Dr Schweitzer was having trouble getting her results published. “I had one reviewer tell me that he didn’t care what the data said, he knew that what I was finding wasn’t possible,” says Schweitzer.
“I wrote back and said, ‘Well, what data would convince you?’ And he said, ‘None.’”
Schweitzer recounts how she noticed that a T. rex skeleton (from Hell Creek, Montana) had a distinctly cadaverous odour. When she mentioned this to long-time paleontologist Jack Horner,2 he said, “Oh yeah, all Hell Creek bones smell.”
But so ingrained is the notion among paleontologists that dinosaur bones must be millions of years old that the *‘smell of death’ didn’t even register with them—despite the evidence being right under their noses.
3 Schweitzer herself does not seem able or willing to escape the long-age paradigm, despite her direct involvement in many of the discoveries.
Note the timeline of these findings across two decades—pointed and regular reminders that something is very wrong with dinosaur-millions-of-years ideas:.."
