New ideas are the foundations of scientific discovery! YOU YOURSELF ARE A REAL TRIP DUDE, if you haven't realized this by now, look again! What the hells your problem? Where the hell are you coming from? You are definitely a mental case! And as always, you result to the use of vulgarity? Dah! Your new name is "toilet mouth." Do you look in the mirror everytime you flush yourself down?
More inanity.
You really think responses such as this actually rebut anything said?
Here's a hint, douchebag. Your favorite response is called an ad hominem. And while they can be fun when sprinkled in for flavor, you use them almost exclusively. You have zero ability to actually respond to what is said, rather only the ability to throw a tantrum about who is saying it.
And as always, you result to the use of vulgarity?
Valich is a fucking cocksucker. How much cock could a valich suck if a Valich could stop sucking cock?
(Pssst. Watch it, douche. I saw you typed... pause *gasp*....
shit... in one of your posts somewhere. The horror. The absolute horror.)
Although, I must admit that you do seem to actually touch a little on topic here:
There is no conclusive evidence that any dinosaurs were warm-blooded and the argument rests on the following points:
Evidence for:
Growth rates: warm-blooded grow faster
Predator/prey ratios: warm-blooded have a higher predator/prey ratio(1:100). Speed and agility.
Rate of evolution.
Similarities with birds.
Parental Care.
Bone Isotope Composition.
Insulation.
Arctic Faunas.
Evidence against:
Gigantothermy Rate.
Respiratory turbinates - turbinate structure as determined by bone structure in All dinosaurs shows that dinosaurs were not warm-blooded.
Lung structure.
The problem being, of course, that you've just arbitrarily put together a list without showing any sources.
Douche bag, here's a hint. Why is it that you seem so certain that dinosaurs are cold-blooded and yet it is a topic that, within the community, is hotly debated and it would seem that, to use one of your favorite terms (which you haven't used in a while... why? Are you sick or something?), the 'general consensus' is falling on the side of
at least some dinosaur species being warm-blooded rather than cold.
But. No. Valich here has provided a list and peremptorily quelled all debate on the subject with his list. Of course, it would seem that his list is longer on the 'for' side than the 'against'. Why is that?
For:
Growth rates: warm-blooded grow faster
Yup. I've read a few articles on this lately. It would seem that many dinosaurs grew much faster than was once thought to be the norm. This is evidence that they were warm-blooded.
Predator/prey ratios: warm-blooded have a higher predator/prey ratio(1:100). Speed and agility.
Hey. Looky looky. You actually understood someone else's post. Congratulations. Of course, you still come off as an ass as this point was made to you in rebuttal to one of your posts and you never acknowledged it. Rather, you've just co-opted it right into your own argument as though it were yours all along. This is why people don't like you. One of the reasons.
Anyway. Yup.
(By the way, douche, this was point one of Ophiolite's list.... Or didn't you realize that? What happened to you saying that Ophiolite's list was all wrong?
Oh. And, while we're on the topic, not to let you squirm out.... What was that you were saying about 4-chambered hearts and their relevency when considering Ophiolite's three points? Come on, douche. Think I'm going to let it slide? (Here's the part where you say I'm nit-picking. It's not nit-picking. It's merely calling you on your bullshit. You expect people to let your bullshit slide, but it's
not going to happen. Douche bag.))
Rate of evolution.
Similarities with birds.
Parental Care.
Yup. Yup. Yup.
Bone Isotope Composition.
Interesting. Isotope composition? When I was talking about bone structure, I was talking about the structure formed by the bone growth. Not it's mineral composition.
Elaborate?
By the way. Since you're such a douche bag and all (I love douche bags. They keep vaginas so fresh and clean) I went out and found that reference on soft tissue found in T-Rex which contains information on evidence towards warm-bloodedness.
Soft-Tissue Vessels and Cellular Preservation in Tyrannosaurus rex
Mary H. Schweitzer, Jennifer L. Wittmeyer, John R. Horner, and Jan K. Toporski
Science 25 March 2005; 307: 1952-1955 [DOI: 10.1126/science.1108397] (in Reports)
The thing is that the bone structure indicates rapid growth and is much more threaded with blood vessels than would be seen in a cold-blooded animal. It's more akin to bird bones than reptile bones.
Yup. And. Again. You've simply co-opted another's point without ever acknowledging to said poster. Asshole. This is also Ophiolite's third point. But.... *gasp* I thought you invalidated his list because crocodile's have
a four-chambered heart!!! Say it ain't so!
In fact, some of the last surviving dinosaurs were arctic models. Tough niche for a reptile.
As to your reasons against:
Gigantothermy Rate.
Respiratory turbinates - turbinate structure as determined by bone structure in All dinosaurs shows that dinosaurs were not warm-blooded.
Lung structure.
Depressingly short, isn't it?
Care to elaborate on any of these? Or were you short on google time and merely had time to gather the words without taking the time to misunderstand them?
