The fossilized leg of an 80-million-year-old duck-billed dinosaur has yielded the oldest known proteins preserved in soft tissue—including blood vessels and other connective tissue as well as perhaps blood cell proteins—a new study says.
The research was led by the team behind the controversial 2007 discovery of protein from similar soft tissues in 68-million-year-old Tyrannosaurus rex bones.
"It was not a one-hit wonder," said John Asara of Harvard Medical School, who led the protein-sequence analysis.
(See a prehistoric time line)
Well-Preserved Dinosaur
The proteins were recovered from a hadrosaur femur that had been encased in sandstone, which appears to prevent complete tissue degradation, Asara said.
Preliminary microscopic analysis revealed structures resembling blood vessels, cells, and collagen, he noted.
Those initial speculations were confirmed by applying antibodies to the tissue that are known to react with proteins. The tests suggested the presence of collagen and other proteins, including hemoglobin, the protein in red blood cells.
Dinosaur Blood Cells?
The hints of hemoglobin remain speculative and are not covered in the new, peer-reviewed study, which appears in today's issue of the journal Science.
Some scientists suspect the hemoglobin is a contaminant.
If it's not a contaminant, "it is much bigger news than [the confirmed discoveries of blood vessels and other connective tissues in] this paper," said Pavel Pevzner, a computational biologist at the University of California, San Diego, who was not involved in the new research.
A confirmed dinosaur-hemoglobin discovery would open the door to the recovery of many dinosaur proteins, including DNA proteins, he noted—raising the specter of Jurassic Park-style "resurrections."
Study co-author Asara said that, so far, there's not much his team can say about the hemoglobin, which is difficult to identify with current technology.
"Although, we don't believe that it is contamination."
Fleshing Out the Family Tree
Asara analyzed the tissue samples with a mass spectrometer, which reveals chemical makeup by telling scientists the masses of different elements in a sample.
He uncovered eight collagen proteins, and a colleague compared them with samples from living animals as well as mastodon and T. rex fossils.
The results placed the duck-billed dinosaur, Brachylophosaurus canadensis, on the same family-tree branch as T. rex. And, as expected, both the duckbill and T. rex were more closely related to chickens and ostriches than to alligators and lizards.
New Respect?
The new study may dispel some of the controversy over the team's 2007 T. rex soft-tissue study—for example, critics argued that the tissue was actually introduced to the specimen through mishandling.
I've seen quotes by Thomas Paine to the same effect, but it seems it's being argued there is no place for people that hold such opinions among political conservativism.
Really, I am confusing the Bible and God. Where exactly would one go to find out who God is, to the evolutionary system thinkers? But of course the Bible has been in the hands of man since its recording, who else should it have been given too.
The 'WORD' as it is called is God, (John 1:1) and the WORD said that in fact busy fingers would do whatever they could to pervert the WORD, nothing new under the sun. I can give you an easy example but surely not the only one. Somebody decided to use the word easter and put it in place of the word Passover. It is possible to verify that even though the majority of Christians attempt to claim otherwise. Why was the House of Israel dispersed into captivity unto the Assyrian king? Because they did not adhere to the WORD. And again there is nothing 'new' under the sun.
Simply, not credible. Some scientists just check their reason at the door.
thanks nick! I’ll add it to the collection:

Pro-evolution is not anti-God. You can (and many do) consistently believe in evolution and the Christian God, much less any god. The exclusivity that you’re emanating on the basis of a fringe belief that flies in the face of all scientific evidence is exactly what I’m talking about.
I can make many assumptions based upon the particular words you have place together to put me in my place.
Christ came through this flesh age and He was perfect in His generations, charted and traced all the way back to that day when the breath of life was breathed into The Adam's nostrils. Now some Christians can dabble in that religion of the god of knowledge and claim it to be of Christ but the evidence is there to discredit the claims.
You are correct in the words you used, 'believe in evolution'. I think there is plenty of evidence I could use to show you that Christ Himself was and is still considered a 'fringe' belief. There was something very exclusive about Christ and it is HE and HIS history that is the evidence that the tale of evolution flies against Him. See now if you are against Christ then you are against God the one who created all things, even that god of the knowledge of good and evil eons before the soul/spirit got housed in the earthly flesh vessel.
thats a very kind analogy. I myself have no problem in believing in God and evolution. They are not mutually exclusive. Indeed,the diversity of life only proves how far reaching the hand of God is.
Correction: "Now get outside and clean up the mess he made of the neighbors."
“The fossilized leg of an 80-million-year-old duck-billed dinosaur has yielded the oldest known proteins preserved in soft tissue—including blood vessels and other connective tissue as well as perhaps blood cell proteins—a new study says.”
Only a fool would still believe that proteins would remain intact after 80 million years. I used to believe that the universe was billions of years old but the Schweitzer discovery made me reevaluate everything. It wasn’t the only thing but it was the primary catalyst.
I checked your reference and remember having the same reaction myself when I read it some three years ago.
It is just incomprehensible that undecomposed red blood cells could exist after 65+ million years.
