Original Animal Protein in Fossils?

mammals, squid, fish…
I first learned about original soft tissue fossils from Creation magazine in 1997.1 What looked like red blood cells and blood vessels from inside Tyrannosaurus bone did not fit what I had been told about how fossils are millions of years old. I immediately understood that the fossil, and therefore the rock layer that held it, could be no older than thousands of years.
At that time, wise scientists warned that further investigations could either invalidate or validate the outrageous find. Now, many discoveries in special pockets around the world have validated many such original animal tissue fossils.
Sometimes ‘soft tissue’ fossils refer to impressions in rock that preserve an animal body outline, like squid, algae, or worm bodies, or of dinosaur skin or footprints. Scientists may also refer to tissue replacement by minerals like phosphate, pyrite, or carbon as ‘soft tissue preservation.’ Stable substances like rocks and minerals can last a very long time, but not so the animal’s original biochemicals.
Reliable techniques have detected chitin, chitin-associated protein, elastin, fibrin, osteocalcin, keratin, hemoglobin, DNA, and collagen, and many other such proteins in various fossils. Comparing the degree of wholeness of the fossil biochemicals to the same biochemicals from modern animal tissue reveals that the fossil material has only partly decayed. Those biochemicals should have completely decayed over any claimed period of millions of years into tiny molecules like carbon dioxide, water, or ammonia. But paleontologists keep finding original biochemistry—like finding mummified remains—encased in rock.
Take collagen, for example. It is a resilient, strand-like protein molecule that strengthens hard mineral in bones and sea (mollusc) shells, and strengthens skin and connective tissue. Collagen’s toughness explains why skin, and thus parchment, is long-lasting. But parchment does not last for even half of a million years. We know this from examining the Dead Sea Scroll parchments. After two millennia, they are quickly turning to dust.
In fact, we know from calculations based on straightforward scientific principles that collagen could last hundreds of thousands of years, and we know that it could not last multiple millions of years. In 2011, UK archaeologists and experts on bone collagen decay wrote that “it will take between 0.2 and 0.7 Ma [million years] at 10°C for levels of collagen to fall to 1% in an optimal burial environment.”2 So, collagen could last 450,000 or so years on average. If kept below freezing, it might be imagined to last one or two million years at the very most. But evolutionists agree that dinosaurs lived in a very warm climate, so in their scenario, this would vastly shrink the times—at 20°C, collagen would have decomposed below the detection limit in about 15,000 years.3,4
However, I have found many reports of collagen-containing fossils designated as tens of millions of years old. Some fossils even have skin or cartilage collagen, which is not encased in protective bone or shell mineral. A number of these reports are listed on a chart published online at the Institute for Creation Research website.5 But I am always finding more.
In the chart, I listed a T. rex collagen protein sequence described in 2005. Collagen fibres from a Psittacosaurus dinosaur were published in 2008. The most thoroughly analyzed original soft tissue fossil so far is the 2009 hadrosaur femur. It was from Hell Creek Formation in Montana, the same formation as the T. rex found in 2005. The hadrosaur’s blood vessels had plenty of original collagen. I even found a report of original dinosaur bone collagen that was found in the Gobi desert in 1966.6
We have a fine fossil fish with original collagen fibres featured on an office wall at ICR (see photo above). It is from the Green River Formation in Wyoming. How do we know it is actually original fish collagen? First, it is a different colour, hardness, and texture from the surrounding rock. One visitor said that it looks like beef jerky. Second, the paleontologists who prepared it wrote that it was collagen. To dispel any doubt, scientists used four independent techniques to directly test fossil lizard skin from the same formation as our fish.7 They wrote,
“Taken together, all the analyses performed in this study strongly suggest that the fossilized reptile skin in BHI-102B [the lizard fossil] is not a simple impression, mineralized replacement or an amorphous organic carbon ﬁlm, but contains a partial remnant of the living organism’s original chemistry, in this case derived from proteinaceous skin.”8
Although collagen cannot last longer than hundreds of thousands of years at realistic temperatures, it is right there in a supposedly 50 million-year-old lizard leg, and a supposedly 50 million-year-old fossil fish. And the dinosaur collagen fossils are supposed to be even older! Clearly, their age assignments are not correct (see box below). Original soft tissue fossils appear to be thousands of years old because that is their actual age range, just as biblical history indicates.
Does other evidence confirm thousands of years?
Those who insist that dinosaur and other fossils are millions of years old often cite radioisotope dates. Although radioisotopes appear to have undergone millions of years’ worth of decay at today’s slow rates, other data shows that those rates were dramatically accelerated in the past. First, rocks of known historical age always yield vastly inflated radioisotope ages.1 Also, the helium leakage age of granites is only six thousand years.2,3 Third, all carbon-containing Earth materials so far tested, including diamond, contain abundant radiocarbon, a tell-tale signature of material that is no more than about 50 thousand years old.4 So their radioisotope ages are all wrong.
Scientists plan to obtain radiocarbon ages of dinosaur bone. In the meantime, a 2011 study reported a radiocarbon age for a fossil mosasaur [marine reptile] bone of 24,600 years.5 Of course, the fossil could be even younger. Age estimates based on radiocarbon decay and based on tissue decay agree on a maximum age range of thousands of years.
Using natural processes such as these for age-dating always requires assumptions. In contrast, the Bible is a collection of reliable eyewitness accounts co-authored by the Creator. It holds straightforward age information, including a tight time range for Noah’s Flood, which occurred around 4300 years ago.
Most of the fossils with original soft tissues were deposited by the waters of that same Flood retreating off of continents about 4300 years ago, consistent with the observation that the tissues have not yet completely decayed.

Excellent article. Apart from anything else, when will evolutionists start applying some common sense?
Re Carl B's question re when evolutionists will see sense, the answer is when they receive the gift of faith that we Christians have been given (viz., "By faith we understand that the entire universe was formed at God's command, that what we now see did not come from anything that can be seen" - Heb 11 v3) and, most probably, not until then.
Praise God for opening our eyes, and thanks also to CMI for helping to open them wider!.
From the Smithsonian magazine re a recent, well documented fossil soft tissue find.
"Schweitzer, one of the first scientists to use the tools of modern cell biology to study dinosaurs, has upended the conventional wisdom by showing that some rock-hard fossils tens of millions of years old may have remnants of soft tissues hidden away in their interiors. “The reason it hasn’t been discovered before is no right-thinking paleontologist would do what Mary did with her specimens. We don’t go to all this effort to dig this stuff out of the ground to then destroy it in acid,”
"Right-thinking paleontologist" indeed!
So much for the predictive capability of evolution vs creation that materialist spokesmen assert.
