Dinosaurs may have been warm-blooded, a finding that could debunk one of the most commonly-held images of the extinct giants.

Researchers in Spain and Norway report in the journal Nature they had found tree-like growth rings on the bones of mammals, a feature that until now was thought to be limited to cold-blooded creatures ... and dinosaurs.

They also found evidence that dinosaurs probably had a high metabolic rate to allow fast growth -- another indicator of warm-bloodedness.

"Our results strongly suggest that dinosaurs were warm-blooded," says lead author Meike Koehler of Spain's Institut Catala de Paleontologia.

If so, the findings should prompt a rethink about reptiles, she says.

Modern-day reptiles are cold-blooded, meaning they cannot control their body temperatures through their own metabolic system - relying instead on external means such as basking in the sun.

While the dinosaurs may have been warm-blooded, their other characteristics kept them squarely in the reptile camp, says Koehler.

Palaeontologists have long noted the ring-like markings on the bones of cold-blooded creatures and dinosaurs, and taken them to indicate pauses in growth, perhaps due to cold periods or lack of food.

The bones of warm-blooded animals such as birds and mammals had never been properly assessed to see if they, too, exhibit the lines.

Koehler and her team found the rings in all 41 warm-blooded animal species they studied, including antelopes, deer and giraffes.

The finding "eliminates the strongest argument that does exist for cold-bloodedness" in dinosaurs, she says.

The team's analysis of bone tissue also showed that the fast growth rate of mammals is related to a high metabolism, which in turn is typical of warm-bloodedness.

"If you compare this tissue with dinosaur tissue you will see that they are indistinguishable," says Koehler.

"So this means that dinosaurs not only grew very fast but this growth was sustained by a very high metabolic rate, indicating warm-bloodedness."

A comment by University of California palaeontologist Kevin Padian that was published with the paper says the study was the latest to chip away at the long-held theory that dinosaurs were cold-blooded.

"It seems that these were anything but typical reptiles, and Koehler and colleagues' findings remove another false correlation from this picture."

we are cold blooded.

cold hearted too, I have no problem ripping the still beating heart out of a young raptor, in fact I find it really fun when done in full view of the mother. The way she weeps and kicks the dirt. Cause what's she gonna do? I could kill her too, but leaving her alive lets her tell the tale. Don't be f*cking with T-Wrecks.

GREAT FIND!!!!!
Except... Immanuel Velikovsky postulated this 70 years ago.
But that is par for the course because many many many of his postulates have been usurped by later "scientists".

The difference is that Velikovsky was ahead of his time and had too many good things to soon which caused them to drum him out of the community of ducks and kiss asses.
Hasn't changed even today when he has been proven right on so many BIG issues.
This world is about POLITICS and MONEY.
Medicine is about politics and money.
Science is about Politics and Money.
Entertainment is about P&M.
Business is about P&M.
Military is about P&M.
Religion is about P&M.

Got that?
Wanta be a successful scientist?
Find one of Velikovsky's postulates and find evidence for it WITHOUT MENTIONING Velikovsky.

really?

2012 and this issue had yet to be nailed down?

Lol

isn't it interesting how anti-ID, Darwinian evolutionists believe that birds WINGs, which are an amazing example of how to design flexible aerodynamic wings that create LOFT......

somehow manifested via the meandering blind random, non-purposed biological mutations of unintelligent design.....
