Your site basically had this to say:
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."
What scientist actually know is this:
Fourth, just because this iron increases the “resistance of these ‘fixed’ biomolecules to enzymatic or microbial digestion” does not necessarily mean that it increases resistance of these “fixed” biomolecules to degrading chemical reactions.1 In other words, these authors have again shown that iron inhibits microbes, but they did not show that it inhibits the oxidation and hydrolysis reactions known to relentlessly convert tissues into dust.
Plus, though they showed how iron ups resistance to microbes for two years, they did not show that it does so for millions of years. Getting these tissues to resist enzymes and microbes is the lowest hurdle. These results fail to demonstrate the next step—getting tissues to resist the laws of chemistry for unimaginable time spans.
While the study does show that iron helps preserve soft tissues, the results fall far short of the authors’ claim that this explains soft tissue persisting for millions of years. Concentrated blood and extra water may not approximate real conditions, iron is not always present with known original tissue fossils, and the scientists did not produce a useful time-to-dust estimate for their iron-encrusted tissues.
By showing that iron particles stuck to dinosaur blood vessels look similar to those attached to ostrich vessels, this research may explain how soft tissues have resisted disintegration for longer-than-expected intervals—for example,
thousands of years. You can learn from the full article by
