I think I've done this before...
5. Both dino and reptile not feathered like bird.
There are plenty of dinosaurs that are known to be feathered.Off the top of my head: SinosauropteryxArchaeopteryx Sinornithosaurus Shuvuuia Rahonavis Microraptor Cryptovolans Omnivoropteryx Caudipteryx Protarchaeopteryx Dilongia Psittacosaurus Scansoriopteryx Epidendrosaurus Beipiaosaurus "Dave" Keep in mind that these are just the ones of the top of my head.Also keep in mind that I don't have the best memory. Lastly, keep in mind that I've looked for information about the latest dinosaur finds only about 3 or 4 times in the past years. And at the curret rate of discovery of about one species per week, that's a lot of information that I've missed. Proudly attempting to Google-Bomb Kent "The Idiot" Hovind's website Idiot

i seriously doubt that's off the top of your head. that's fairly inclusive list, actually.
frankly, i'm amazed we know of that many considering how rare it is for soft features like feathers to fossilize. do we even have that many examples of regular dinosaur skin? (and is it possible that a majority of dinos actually sported feathers towards the late cretacious?)

1. You have no idea as to the migratory extent of Dinosaurs. he may not, but i do. some dinosaurs did, in fact, migrate. we know that certain ceratopsians did.
You have no idea about the vocalisations of dinosaurs. If the cranial morphology of Parasaurolophus is anything to go by, I would say that you were most likely premature in your judgement i saw that one! that was a fun show! and boy, it sure did sound like a giant scary bird.

Arach, how many of these feathered creatures have been positively confirmed to be, in fact birds and not dinos? And how many of these have fossils with actual fossilized feathers in/on the fossil?

Buzsaw,
I consider size as valid a synapomorphy, and as relative to the debate as some of CF's points for his arguments. So a snail is the closest relative of a bird if it is the same size? I am more closely related to someone on the other side of the world because I weigh the same as them, & not my brother because he's a stone lighter? Regardless, you made the point that both dino and reptile generally larger than birds, & I pointed out that most reptiles are smaller than the largest birds, rendering your homology moot.
That doesn't cancel out my point. All limbs are not legs. In which case therapods have 2 legs & 2 arms, & not four legs as you claim, do you have four legs? You said, "Both dino and reptile have four legs. Bird two legs, 2 wings". The comparison/homology is therefore invalid. Point moot.
Of course, but how does that negate my point? As has been pointed out by others, most birds spend relatively little time in the air, making them primarily terrestrial. Moreover, you said, "Both dino and reptile land creatures. Bird generally flying creature". So what? you can't show relationships with differences, only homologies. That's like saying bats aren't mammals because they fly & cows don't.
I believe no actual feathers were established on mononykus and views like the one below show that it is speculative as to whether these are early ratite birds or dinos. Taking Caudipteryx as a more detailed example: Caudipteryx possesses 22 caudal vertebrae (a la any therapod), a stiff distal portion of caudal vertebrae, again like a bipedal therapod. The distal caudal vertebrae are short as in therapods, as opposed to elongate as in Archaeopteryx & other Aves. A quadratojugal sutured to the quadrate. The dorsal squamosal process is long. Birds, even basal ones like Archy & Confuciornis have small quadratojugals, Caudipteryx has a long one consistent with it being a therapodan. The obdurator process of the ischium is large & triangular "exactly" like other oviraptor/dromaeosaurid therapods. The jugal is a typically nonavian therapodan jugal with a very large postorbital process. Deep mandibular fenestra, evidenced by the deep caudal embayment of the dentary of the paratype skull. As a point of order, the absence of a mandibular fenestra characterises aves vis-a-vis therapods. The mandibular fenestra of Caudipteryx is again highly comparable to dromaeosaurids & oviraptosaurs. The thoracic girdle possesses none of the avian apomorphies. The coracoid is more or less that of a conventional coelosaur coracoid, with a quadrilateral shape, proximal supracoracoidal nerve foramen, & moderate biceps tubercle. The thoracic girdle is located on the lateral aspect of the thorax with the scapula at an angle to the axial column rather than on the dorsal aspect of the thorax with the scapula parallel to the column. The latter condition is observed in all birds. The former in coelosaurs et al. The ilium is very tall directly above the acetabulum, & its preacetabular portion is not expanded cranially; the typical condition for most nonavian coelosaurs. This is why Caudipteryx is cladistically classified as an oviraptorsaurian (Zhou & Wang 2000), & not placed in the Aviala clade, much less Aves. (Mesozoic Birds. Luis M. Chiappe, & Lawrence M Whitmer) These issues were raised partially in response to Feduccia's claims. Although Feduccia does point to some genuine homologies, cladistic analyses show these to be plesiomorphies, a bit like birds & bats possession of wings not being indicative of common descent. The conventionally accepted conclusion is that Caudipteryx falls easily into the therapodan clade, the reason is that objective cladistic tests that account for all relevant morphological characters place them there. Feduccia, like yourself are more interested in plucking a few characters that support your position at the expense of the majority that contradict you. Making an easier to understand case, Caudipteryx dromaeosar/oviraptosaurid apomorphies, & lacks Aves apomorphies, ergo it is a dromaeosar/oviraptosaurid, not an avian. A point curiously ignored by Feduccia. Nonavian dinosaurs have feathers, rendering your point 5 moot.
Again, these are rare oddities. How many dinos had toothless beaks? Irrelevant. You said, "both dino and reptile mouth and teeth unlike beaked bird". Since some birds have teeth, & some reptiles have beaks, you don't have a pure apomorphy.
That, imo, would be highly unlikely, given how few land animals migrate presently, and of course, it would be difficult to migrate any significant distance. Your "imo" is neither here nor there. Since some large animals do migrate, you need positive evidence that dinosaurs didn't. No evidence = moot point.
Good. That may be a plus for the Biblical record and my hypothesis as well, since it would implicate at least one Edenic dino as communicating with humanity. Likely, though it would be too volumnous for birdlike sounds. Whatever you say, Buz, but for the purposes of this thread, point 8 is moot.
mark writes: 9. False. Therapodan legs are almost identical in layout to bird legs. In fact it would be difficult to find two tetrapod leg layouts that could be more different than crocodile/birds.
buz writes: I've already addressed this in that the Creator would likely have made some necessary adjustments to compensate for the adjustment to short legged reptiles and snakes. I am not interested in your "creator may have" stories, I am directly countering your claim that reptiles & birds legs are more similar to each other than birds/dinosaurs. This is an absolutely false claim for the reasons already given.

None of them have been positively confirmed to be birds and not dinosaurs. Shuvuuia may be a bird, and it still is generally thought that Archaeopteryx is a bird, although there is more and more evidence that it is not a bird.
All of them but Rahonavis have preserved feathers, but Rahonavis has rather obvious attachment points for feathers on its arm bone. The humerus, I think. It might be one of the other two. [i]Shuvuuia[i]'s feathers are difficult to make out, but were conclusively shown to be feathers when an analysis of the chemical structure of the fossilized proteins revealed them to be a specific protein (the name of which I can't remember. Beta-keratin or something.) that is only found in feathers. Proudly attempting to Google-Bomb Kent "The Idiot" Hovind's website Idiot

It is off the top of my head. You can tell because I spelled Dilong incorrectly.
The only reason we know of so many is because of a volcanic eruption in China about 100 or so mya. Out of all the dinosaurs I listed, only 3 were found outside of the Yixian. (And if you want to be picky, Rahonavis was not found with preserved feathers, only with attachment points for the feathers.) We have several preserved examples of dinosaur skin, including ones from a hadrosaur, Carnotaurus, Aucasaurus (I think.), a titanosaurid, and Tyrannosaurus rex. We also have several instances of preserved soft tissues that aren't feathers. Muscles in Pelecanomimus, a four-chambered heart in Thescelosaurus, intestines in Scipionyx, and a layer of subdermal (I think that's the word.) fat in Psittacosaurus. (The same one that had the quill-like structures on its tail that are most likely feathers of some kind.) On an aside, we also have preserved integument from pterosaurs, which, along with dinosaurs, make up the clade Ornithodira. Specifically, we find this in Sordes. Due to the relationship between dinosaurs and pterosaurs, it would make more sense that this integument is somehow related to feathers, as it is more likely for a feature to evolve once in two closely related groups that it is to evolve once per group.

How many then, have been positively cornirmed to be dino and positively not birds?

Buz, what a lot of these critters are, are transitionals, the steps between dinosaur and bird, missing links. Yet more support for both Evolution and the TOE.
edited to add: The designation of Dinosaur or Bird can get pretty hard. They are, afterall, arbitrary. If they are more bird-like than dinosaur-like we may call them bird. But it is not an absolute, as we learn more, find more examples, more observations, the assignments may well sift. We're dealing with both what is there and with our own arbitratry nomenclature. We we look at examples of critters from millions of years ago, billions of years ago, and tried to make them fit neatly into our pigeonholes, it often is simply a choice which hole we put them in.

So a snail is the closest relative of a bird if it is the same size? LOL. It would be if it had enough other similarities (as I believe crock has) to qualify to be. You people are forgetting, it appears that my hypothesis factors in a substantial renovation of the physiology of the Edenic serpent accordig to the Genesis text.
Regardless, you made the point that both dino and reptile generally larger than birds, & I pointed out that most reptiles are smaller than the largest birds, rendering your homology moot. A few reptiles are larger than any bird. Not a big deal, but, imo, has some significance.
In which case therapods have 2 legs & 2 arms, & not four legs as you claim, do you have four legs? You said, "Both dino and reptile have four legs. Bird two legs, 2 wings". The comparison/homology is therefore invalid. Point moot. Do their arms have hands or do they have feet similar to their hind feet? What did they use these front limbs for?
As has been pointed out by others, most birds spend relatively little time in the air, making them primarily terrestrial. By the same token my point is that they do spend some time flying.
Moreover, you said, "Both dino and reptile land creatures. Bird generally flying creature". So what? you can't show relationships with differences, only homologies. That's like saying bats aren't mammals because they fly & cows don't. As I've already posted, many species have their flukes.
Irrelevant. You said, "both dino and reptile mouth and teeth unlike beaked bird". Since some birds have teeth, & some reptiles have beaks, you don't have a pure apomorphy. As I've already posted, many species have their flukes.
I am not interested in your "creator may have" stories, I am directly countering your claim that reptiles & birds legs are more similar to each other than birds/dinosaurs. This is an absolutely false claim for the reasons already given. My point has been that since it's a given my hypothesis would have the post-cursed offspring a different physiological reptile, there will be significant adjustments The debate boils down to whether bird or reptile would best explain the evidence for the Edenic serpent with legs to have existed. After all, this bird/dino debate started from that premise in my hypothesis. For my hypothesis to have credibility, and for Genesis record to have credibility, after all, we must, like you evos, come up with some evidence for what we believe. I believe dino's fossils is my evidence for Edenic serpent. I also believe my hypothesis is the best answer for the fact that all dinos disappeared and what happened to them. You people may disagree and thats your perrogative. This's my perrogative.

Well, they range from around 120 Million years ago to about 200 Million years ago. That seems back a ways.

All of them but Archaeopteryx and Shuvuuia. But like jar said, the line between dinosaurs and birds is arbitrary.

quote: Archaeopteryx. Have you simply not paid attention to the various fossils showing feathered dinosaurs?
quote: If you watch the embryological development of birds, you find that they do, indeed, have teeth. But during their development, the body absorbs the teeth. That's why we have the phrase, "As rare as hen's teeth." Every now and then you find a bird that has teeth. Note, baleen whales have the same process. One of the characteristics of all mammals is their teeth. But, baleen whales don't have teeth in their final form, so what gives? Simple: Look at the embryological development and you find that baleen whale embryos do have teeth that get absorbed. Why would god create a creature that develops teeth it never uses and needs to absorb back into the body?
quote: Irrelevant. Lizards, being cold-blooded, tend to live in areas that get enough warmth to keep them active. Thus, they have no need to migrate. Birds, being warm-blooded, don't have that restriction.
quote: As others have pointed out, you have no idea what a dinosaur sounded like.
quote: Incorrect. Lizards have legs that come out the side with five toes. Dinos and birds have legs that come out the bottom with three toes. Rrhain WWJD? JWRTFM!

Psittacosaurus. (The same one that had the quill-like structures on its tail that are most likely feathers of some kind.) really? see what happens when i don't follow paleontology for a while? got any links for that? i'd really be interested in seeing a picture of that, or at least an article. you seem to know a lot about the field. are you a working paleontologist? i wanted to be one when i was a child, but sort of lost interest at some point.
