Neatly dressed in blue Capri pants and a sleeveless top, long hair flowing over her bare shoulders, Mary Schweitzer sits at a microscope in a dim lab, her face lit only by a glowing computer screen showing a network of thin, branching vessels. That’s right, blood vessels. From a dinosaur. “Ho-ho-ho, I am excite-e-e-e-d,” she chuckles. “I am, like, really excited.”
After 68 million years in the ground, a Tyrannosaurus rex found in Montana was dug up, its leg bone was broken in pieces, and fragments were dissolved in acid in Schweitzer’s laboratory at North Carolina State University in Raleigh. “Cool beans,” she says, looking at the image on the screen.
It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T. rex bone—the first observation of its kind. The finding amazed colleagues, who had never imagined that even a trace of still-soft dinosaur tissue could survive. After all, as any textbook will tell you, when an animal dies, soft tissues such as blood vessels, muscle and skin decay and disappear over time, while hard tissues like bone may gradually acquire minerals from the environment and become fossils. 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,” says dinosaur paleontologist Thomas Holtz Jr., of the University of Maryland. “It’s great science.” The observations could shed new light on how dinosaurs evolved and how their muscles and blood vessels worked. And the new findings might help settle a long-running debate about whether dinosaurs were warmblooded, coldblooded—or both.
Meanwhile, Schweitzer’s research has been hijacked by “young earth” creationists, who insist that dinosaur soft tissue couldn’t possibly survive millions of years. They claim her discoveries support their belief, based on their interpretation of Genesis, that the earth is only a few thousand years old. Of course, it’s not unusual for a paleontologist to differ with creationists. But when creationists misrepresent Schweitzer’s data, she takes it personally: she describes herself as “a complete and total Christian.” On a shelf in her office is a plaque bearing an Old Testament verse: “For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future.”
It may be that Schweitzer’s unorthodox approach to paleontology can be traced to her roundabout career path. Growing up in Helena, Montana, she went through a phase when, like many kids, she was fascinated by dinosaurs. In fact, at age 5 she announced she was going to be a paleontologist. But first she got a college degree in communicative disorders, married, had three children and briefly taught remedial biology to high schoolers. In 1989, a dozen years after she graduated from college, she sat in on a class at Montana State University taught by paleontologist Jack Horner, of the Museum of the Rockies, now an affiliate of the Smithsonian Institution. The lectures reignited her passion for dinosaurs. Soon after, she talked her way into a volunteer position in Horner’s lab and began to pursue a doctorate in paleontology.
She initially thought she would study how the microscopic structure of dinosaur bones differs depending on how much the animal weighs. But then came the incident with the red spots.
In 1991, Schweitzer was trying to study thin slices of bones from a 65-million-year-old T. rex. She was having a hard time getting the slices to stick to a glass slide, so she sought help from a molecular biologist at the university. The biologist, Gayle Callis, happened to take the slides to a veterinary conference, where she set up the ancient samples for others to look at. One of the vets went up to Callis and said, “Do you know you have red blood cells in that bone?” Sure enough, under a microscope, it appeared that the bone was filled with red disks. Later, Schweitzer recalls, “I looked at this and I looked at this and I thought, this can’t be. Red blood cells don’t preserve.”
Schweitzer showed the slide to Horner. “When she first found the red-blood-cell-looking structures, I said, Yep, that’s what they look like,” her mentor recalls. He thought it was possible they were red blood cells, but he gave her some advice: “Now see if you can find some evidence to show that that’s not what they are.”
What she found instead was evidence of heme in the bones—additional support for the idea that they were red blood cells. Heme is a part of hemoglobin, the protein that carries oxygen in the blood and gives red blood cells their color. “It got me real curious as to exceptional preservation,” she says. If particles of that one dinosaur were able to hang around for 65 million years, maybe the textbooks were wrong about fossilization.

This isn't the only instance either. There is one of the "dinosaur mummy" ...skin, ligaments, etc found with the bones.
http://news.nationalgeographic.com/news/2007/12/071203-dino-mummy_2.html
And numerous other similar discoveries by Otis Kline and others where soft tissue was discovered.
Amazing feat that not just once, or twice or even three times that soft tissue or skin lasted 60-70 millions years old.
Unless ...it's not really 60-70 millions of years old.
Then average in that less than 1% of fossilized bones that have been cataloged are vertebrates... and of this small percentage there was "luck" enough to find ones with soft tissue. Amazing!

I think I found a bone I would like you to take a look at it how would I show u it

M.E.2 posted: ""The passage about god talking to Job is about a hippo, not a dinosaur. Fail."" You are wrong, sorry. Have you seen the tail of a hippo or an elephant?? NOT a cedar tree! I have a study bible where the commentary says the verse is about a hippo or an elephant, but almost all bibles have been influenced by the theory of evolution. Unfortunately with the pressure to conform to the thought that the world is billions of years old, they did (I bet Satan loved that one!!). Read the King James Version or go back to the original greek and hebrew. God created the world in 6 days, dinos included!! Science is still trying to catch up to the Bible. As science advances We are able to prove the word is accurate and trustworthy.. Science has never been able to PROVE the word of God incorrect. One day all the evolution believing Christians will have their eyes opened and they will surely say, “I can’t believe I fell for that”.

Preston writes, "The "collagen," according to these responses, is more likely some sort of microbe that fed on the original substance."
That simply begs the question: how can "some sort of microbe" or "biofilm," as the pseudo-scientists call it, have survived for 70 million years? You still have the problem of how organic material avoided complete decay for so long.

Soooo... they obviously aren't millions of years old after all.

@ M.E.2: Unless a hippo has a tail like a cedar, I think your assumption is a fail.

There has been a strong response to this among the scientific community, and some very justified criticism. Her theory comes about because someone unrelated to her field saw something that looked to them like red blood cells. There are competing theories now, since virtually any sphere containing iron will look like a red blood cell and similar "cells" have been found in ammonite fossils where no blood would have been located. The "collagen," according to these responses, is more likely some sort of microbe that fed on the original substance.

The passage about god talking to Job is about a hippo, not a dinosaur. Fail.

I have done quite a bit of reading on this topic. Very very interesting! Couldn't help but think about the Coelacanth; 'extinct' 65 million years ago, with the dinosaur, but still swimming around today looking exactly like the '65 million' year old fossils!!!

If anyone doubts that there is a concerted effort to quash any "scientist" who dares challenge macro evolution, just go to wikipedia and search Richard Sternberg. He is one of many highly credentialed scientists who have been fired for bucking the Darwinian system. What a shame that true critical thinking has come under attack by those who espouse the same.

I would just like to point you to an article I have just read, it states:-
"in Montana 2005 field palaeontologist Otis Kline and his excavation team unearthed fossils from a triceratops and a hadrosaur. These specimens came from the same Hall Creek formation as the Schweitzer T-rex. They were also in good condition and the team was propelled to determine if these, like the T-rex still contained some fresh remains that hadn't yet fossilised.
Both the dinosaurs still possessed collagen!!
Otis Kline & another Scientist, Hugh Miller, were eager to test both of these dinosaurs for Carbon 14.
Due to the significance of this study, the industry-recognised Accelerated Mass Spectrometer (AMS) was used to test for Carbon 14. Furthermore, not one but two internationally recognised labs, Geochron Laboratories and the University of Georgia Isotope Center were used so that the results could be independently confirmed.
The tests yielded paradigm-shifting results: BOTH bones contained Carbon 14
According to the AMS testing, the Triceratops registered, on multiple tests an average age of 30,890 ±380 years old.
The Hadrosaur was tested to be 23,170±170 years old (Josef Holzschuh, Jean Pontcharra, Hugh Miller, Recent C-14 Dating of Fossils Including Dinosaur Collagen, Nov 2009)
The Evolution believing Scientists who found and tested the T-rex bone, Refuse to carbon date it, because they say it is impossible as it is 65 million years old. Are they afraid it will cause them even more problems.

"After 68 million years in the ground..." I still can't believe people are this dumb. Bones and/or soft tissue CANNOT remain in the ground intact for that long. This is just proof positive that folks who believe in evolution are simply dishonest, liars, and deliberately deceptive. They follow the true science that speaks so clearly. A logical thinking person would question the number of years those bones were in the ground before raising any other question.

Good video to see on this subject can be found at http://www.youtube.com/watch?v=6hhsx80P1PQ. The evolutionsits have gone to great lengths to try to debunk the consistent C-14 dating of dinosaur bones which show them to be less than 10,000 years old!

The question should be, why there is no decay? Rapid burial under tons of water pressure may be the answer for the remarkable condition of these fossils. You will not find so well preserved fossils after the ice age because of decay.
The answer may be found in the Bible. Many earth science discoveries were found from understanding the Bible.
