The new scientist link doesn't even work.... Good try though, but how in the hell do the last two links help your argument?
"Currently, most paleontologists believe that dinosaurs were somewhere in between warm- and cold-blooded. Dr. Jack Horner at the Museum of the
Rockies, Montana State University has been doing a lot of work with the bone histology (cell structure) of mammals, dinosaurs, birds, and reptiles. He
has found that dinosaur bones have a lot of blood vessels running through them, similar to birds and in contrast to very few blood vessels in
reptiles. This would indicate that dinosaurs had metabolisms that were higher than is seen in modern reptiles, and more similar to modern birds.
The media often seems to portray the warm- vs. cold-blooded debate as something that paleontologists are either completely confused about, or that we
are arguing about with hammer and tongs. I don't know of any reputable paleontologist who would tell you that dinosaurs are the sluggish,
cold-blooded beasts they were originally thought to be. If anything, the "debate" is more centered on physiology and mechanisms for temperature
"A Fossilized Dinosaur Heart Found
Recently, a fossilized dinosaur heart was discovered. This powerful, four-chambered pump belonged to Thescelosuarus, a lated Cretaceous Period
ornithopod (a plant-eater). This 66 million year old heart has recently been analyzed -- it may have four chambers and a single aorta, which is quite
different from existing reptiles, but is similar to modern warm-blooded animals. However, Tim Rowe, Earl McBride and Paul Sereno think that the
"heart" is an ironstone concretion.
If true, the discovery of a four-cha,bered heart suggests not only that Thescelosaurus may have been warm-blooded, but that many other dinosaurs may
have been warm-blooded as well. This is because we now perhaps have evidence of warm-bloodedness in both Ornithischia and Saurischia (the two major
groups of dinosaurs, which diverged early in the Mesozoic Era). Thescelosaurus was an ornithischian; birds, which are known to be warm-blooded, are
Gee, I dunno, I may be all stupid and crap like that, but sure an hell sounds like the evidence points more closer to warm blooded... you dolt.
