I'm surprised you brought up an article that mentioned the "iron".
Iron lady
Iron is an element present in abundance in the body, particularly in the blood, where it is part of the protein that carries oxygen from the lungs to the tissues. Iron is also highly reactive with other molecules, so the body keeps it locked up tight, bound to molecules that prevent it from wreaking havoc on the tissues.
After death, though, iron is let free from its cage. It forms minuscule iron nanoparticles and also generates free radicals, which are highly reactive molecules thought to be involved in aging.
"The free radicals cause proteins and cell membranes to tie in knots," Schweitzer said. "They basically act like formaldehyde."
Here's the backroom baseball talk concerning that...
When I talk on this subject with Evos and ask how the biomaterial can survive for 65 + MY's I generally get 2 answers. The first is often I don't know, it just does somehow while the second is that it is preserved by iron. Mary Schweitzer needed a way to preserve the biomaterial or the concept of deep time will unravel. She concluded iron would do the trick. But in order to get it to work a lot of preperation had to be performed.
In order to conduct the experiment and have hopes of it working here's what they had to do...
They used Chicken and Ostrich blood because they thought they were the closest to dinosaurs.
Put in an anti-coagulant
Put it in a centrifuge to remove serum.
Put it in a centrifuge to take out platelets
Took out white blood cells
Purified and broke down the red blood cells and added a chemical to expose the hemoglobin which contains iron atoms to do the preserving.
Tissue was then soaked in the modified blood for 2 years in a laboratory environment. That is, no insects, water, microbes, plant roots etc were present….which would have been present when the organisms were buried.
From the heavily modified blood Mary Schweitzer was able to extrapolate 2 years into 65+ MY's and suggest that's how the biomaterial may have been preserved.
But, as we all very well know in the natural conditions the blood would have clotted and hardened and the iron would not have been available.
Is iron the answer...no Gus, it's not.. Iron fails.
Yeah, that process mimics the real world. Right Gus?
