Dinosaur fossils, it was long thought, are simple objects. The fossilization process leaves the overall shape of a dinosaur's bones intact, but all the microscopic structures inside them — the blood cells, connective fibers, and other sorts of soft tissue — inevitably decay over time.

The photo above, from a new study published today in Nature Communications and led by Sergio Bertazzo of Imperial College London, shows an extremely zoomed-in view of a 75-million-year-old theropod claw, taken from the London Natural History Museum's collection. When researchers scraped tiny pieces off the fossil and looked at them under an electron microscope, they found tiny structures that look a lot like collagen fibers present in our own ligaments, tendons, and bones.
In other dinosaur fossils, the researchers found features that resemble red blood cells. Tests showed that they have a similar chemical composition to the blood of an emu (a bird thought to be a relatively close relative to dinosaurs).

The idea that dinosaur fossils might harbor soft tissue first surfaced about a decade ago, when paleontologist Mary Schweitzer found evidence of blood cells preserved inside T. rex fossils.
But what's so exciting about this new study is that the fossils used, unlike Schweitzer's, aren't particularly well-preserved. Susannah Maidment, one of the paleontologists who worked on the paper, called them "crap" specimens. If they have preserved soft tissue inside them, it could be a sign that thousands of other fossils in museum collections do too.

I read about the process more than ten years ago.
It is a lot like the way they make gelatin.
The soak everything in acid until the bones, ligaments, hair and nails are gone, then they neutralize what’s left to remove the acid and then wash what’s left. This process separates the collagen and other soft tissues from the hard stuff.
I suppose you could take it one step further and grind it into a fine powder and call it dinosaur gelatin.
Is that a photo of Kukla, Fran and Ollie in the back ground?
At my age that is the first thing I saw!
Bingo. It’s simply a mathematical impossibility that you are going to find preserved soft tissue remains in something 75 million years old. It is beyond the realm of possibility unless these same atheist evolutionists want to call it an outright miracle.
Anything they are seeing with these structures still intact can’t be more than some number of thousands of years old.
But that wrecks their narrative and smashes their belief system. So they choose to believe something far more improbable rather than face evidence screaming at them in all its soft-tissue glory.
Dino fossils. Soft tissues. Blood cells. Millions of years? No. And deep down they know it.
Thanks for the correction!
“For some reason, I didn’t see it earlier when posting the thread.”
Not your error. Apparently someone at Vox threw in the Emu blood photo after the writer wrote his piece.
Oh oh I vote for a petting zoo.
Wait just a cotton pickin’ minute!
You mean to tell me that Darwin’s preconceived notions might not be true after all?
Next thing, you’ll tell me that Al Gore’s preconceived notions might not be true after all....

Raptor Claw Tetrazzini
Raptor Claw Tetrazzini combines cooked vermicelli, VelociRaptor, and mushrooms with a rich sherry–Parmesan cheese sauce. The mixture is sprinkled with breadcrumbs and Parmesan cheese and baked until bubbly and golden. This is a great way to use leftover cooked VelociRaptor.
Parmesan is full of flavor, so a little goes a long way. We recommend buying the real thing, which has Parmigiano-Reggiano printed on the rind. It has a sharper taste and a firmer texture than domestic Parmesan.
There were witches in North America 300 years ago. They are pretty common now as well.
A “mathematical impossibility”? I’m looking forward to seeing your theorem. Please show your work.
“... The original specimen was collected from ...”
And where, pray tell, did they find this later smiling specimen with the soft tissue?
Totally unexpected. I always assumed they had hydraulic fluid in them.
Crocs caught in the Gulf Stream could survive and arrive in Europe
Hello lunch, says the Dino to the kid.
More like, hello, mid-afternoon snack.
That first picture looks more like a salad bar...
