It was considered impossible for original soft tissue to still exist in dinosaur bones. When just such finds were first reported, detractors said those reporting it were lying. They then said the researchers were incompetent and there was nothing but a “biofilm” actually found. Evidence continued to be published and those arguments were thoroughly debunked, leaving the serious question as to how these soft tissues could possibly survive for millions of years – contrary to the expectations of chemistry and biology.
It is now being promoted that this problem has been solved! Iron molecules act like formaldehyde and do the magic. Is this so? What has really been demonstrated? Below are links to two articles discussing this from a creationist perspective, along with their intro/abstract. Be sure to listen to the podcast for more info.

Iron may paradoxically be the key, claim evolutionist researchers, to preserving dinosaur soft tissue for evolution’s assumed millions of years. More specifically, highly reactive iron atoms are released from proteins when an organism dies; while the organism is alive, iron is sequestered in useful proteins, thus preventing it from participating in destructive chemical reactions. It remains impossible to demonstrate just how long such preservation has lasted, despite the evolutionist claims that iron-induced preservation could last millions of years.
Dinosaur soft tissue
In seeming desperation, evolutionists turn to iron to preserve the idea of millions of years.

Bone cells discovered by Schweitzer, showing classic appearances including nuclei and connecting fibrils—from a Brachylophosaurus allegedly 80 million years old!
Dinosaur soft tissue in fossil bones!? Nearly every CMI speaker has watched incredulous looks on people’s faces as pictures from a 2005 Science magazine article flash on-screen. These show transparent, branching flexible blood vessels and red blood cells alongside soft and stretchy ligaments from a supposedly 68 million-year-old T.rex bone. The remarkable discoveries by palaeontologist Dr Mary Schweitzer have rocked the scientific world.
