"Did you look at the slides? There were actual blood vessels w blood inside. Here’s a quote:"
Yes, I read the site you gave, and the original articles describing the finds.
The remains found are proteins. The proteins can still hold the shape of the structure they came from helping to indicate where they came from.
Shweitzer, for instance, believed that some of the remains were those of red bloods because of the shape of the remains.
Here's a quote from the site you linked:
"Several analytical techniques were used to characterize the material to include nuclear magnetic resonance (NMR), Raman resonance and Raman spectroscopy (RR) and electron spin resonance (ESR). These techniques did identify the presence of heme group molecules ranging in size from between 5,000 and 30,000 daltons (between 35 to over 200 amino acids in size), but the detection limits of these methods were not able to rule-out or rule-in the presence of hemoglobin or myoglobin proteins due to the small amount of specimen available."
What they are looking at are proteins. And note that the amount found was so small that it was difficult to analyze, even with the latest technology.
They then had the clever idea of testing for an immune response in rats.
This worked because, as Shweitzer explained on the site: "Immunogenicity is not dependent on fully intact protein, and even very small peptides are immunogenic when complexed with larger organic molecules . . . even after extensive degradation has occurred."
We're not even talking about whole proteins here, just bits of protein.
"Does that really sound like a 65 million yo specimen to you?"
It depends what you're comparing it to. If mammoth CARCASSES are found with which one could hold a mammoth BBQ, that are tens of thousands of years old - then how old do these massive fossilized bones with microscopic protein bits protected deep inside them appear to be?
“Shweitzer, for instance, believed that some of the remains were those of red bloods because of the shape of the remains.”
No, she didn’t. She didn’t recognize red blood cells at all because she wasn’t expecting to see any. It took a veterinarian to recognize blood cells, because he wasn’t blinded by evolutionary assumptions. The vet, according to Shweitzer, turned out to be right.
Now how about you explain why she missed something this obvious. & while you’re at it, explain her boss’s reaction. Why did he immediately dismiss the possibility that she had discovered blood cells? [& spare me the routine about them not being blood cells. There is a photo of the cells still in the vein. That’s how the vet was able to recognize them & call them to Shweitzer’s attention. (Then there’s Shweitzer’s own identification of the round red discs as blood cells. Look it up.)]
