Deep inside the single leg bone of an 80-million-year-old duck-billed dinosaur, scientists have found a hoard of proteins and blood cells providing the first clear biochemical evidence that dinosaurs are indeed the ancestors of modern birds - linked by evolution.
Until now those links had been based mainly on physical evidence - on feathers from dinosaur fossils, on their fossil eggs, on their fossilized birdlike nestlings and on the close resemblance of dinosaurs and birds like the famed "flying dinosaur" called archaeopteryx.
Now the same team of scientists, which found similar biological material in a 68-million-year-old Tyrannosaurus rex two years ago and immediately faced indignant challenges from many other researchers, has found striking confirmation in the details of their newest discovery.
The scientists say that the biological material they analyzed in their new study shows the strongest chemical relationship yet with similar bone and blood cells and proteins of two modern bird species - ostriches and chickens....

Well, there you have it. Since both have living material, the dog has evolved from the rutabega.
If that track is real, then the “human”’s big toe must’ve weighed 10x the rest of its body. Why else would that indentation be so deep?
Looks like a fake to me or perhaps that’s not a ‘human’.
Yeah, that is one really weird looking footprint!
What I do not understand is how they could find proteins that old. Radioactive decay of Carbon would indicate there is no Carbon left.
Isn't the human print over lapping the dino print?
It looks that way cause the guy was running. Hope he made it.
Radiometric carbon dating always indicates more carbon on allegedly old fossils than should be there. Evolutionists claim that the carbon detected is simply background contamination from ground water. At least some creationists like me, counter with, "if groundwater can contaiminate the fossil with carbon, can't it just as easily wash carbon out of a fossil?"
Will we now have to give libe “the dinasour” when we properly salute them?
No. The fake dino claw cuts into the human foot print.
let me help you out here... http://www.howstuffworks.com/carbon-14.htm
From what I can see from the evidence presented, it would appear that subject "Dino" was following subject "Fred" out of the cave. Therefore, it is likely that the dinosaur footprint was overlaid on top of the human footprint.
They do a good job of explaining the 1/2 life period, however, they fail to address the one crucial element that is rooted in the scientific method. Observation. Starting with Carbon 14, who has observed Carbon 14 decaying to 1/2 of its original component 5,730 years ago? How about Thorium 232 and 14 billion years?
Carbon atoms come in a couple of “flavors” called “isotopes”. The vast majority of carbon atoms are of the variety known as Carbon-12 (they have 6 protons and 6 neutrons in their nucleus). These Carbon atoms are stable and last, for all intents and purposes, forever. A certain (and rather well established) percentage of Carbon atoms come in the flavor of Carbon-14 (they have 6 protons and 8 neutrons in their nucleus). These atoms of Carbon are not stable, and will eventually undergo a process called beta decay to “balance” the number of Protons and Neutrons in their nucleus. When it does, it changes into a Nitrogen 14 atom. The other “normal” Carbon atoms are unaffected. There will always be Carbon present in an organic sample, no matter how old. It is only the UNSTABLE Carbon atoms that decay. Now, after several million years, you won’t find much of any Carbon-14, as it has a half life of about 5700 years or so.
Collagen proteins also link dinosaurs to frogs and newts so a chicken leg is just another variety of a frog leg? Don’t tell that to the French!
It’s humorous that you’re talking about carbon dating in the context of this article, yet no carbon dating was used, no carbon dating was claimed. Nobody uses carbon dating on fossils this old since it’s only accurate out to 45,000 years, 60,000 tops.
