Again, click the links in your own link. It concedes that its flight abilities are debated, and that it wasn't exactly the best flyer out there. Meaning they weren't filling the skies like you see birds doing today. More than likely it was able to make small point to point flights, and that's about it. Its skeletal and feather structure do not allow for full avian flight.

You'd know that by reading the link I posted Smile


Yes it's flight ability is debated, so if there was real hard evidence, there would be no debate. So it appers what you believe about this bird is really up to the toss of a coin. However, this would not be considered good science.
My beliefs are based on facts, not guess work, or blind faith. The only thing that can be said for sure is this was a bird that could fly. How well it could fly, is up for debate.

Nope these animals aren't related at all Very Happy

Well as usual, when we have nothing else, we bring out the artistic drawings, and then try to pass them off as scientific evidence. lol

Ok, don't listen to answersingenesis, consider Nature magazine, they will tell you the same thing. "with every new Archaedpteryx fossil discovery it was realized that the animal cannot have been half-bird and half-reptile."
Or maybe Science Magazine, "True birds have existed at least as long as Archaeopteryx, so that the latter could hardly have been their ancestor."

The hard evidence is what brings up the debate of its flying capabilities. Its skeletal structure, feather structure and joints all question its ability to fly, not support it. Ostriches have wings and feathers, but do they fly well? Why not? Ever seen a flock of chickens in the sky? Why not? They're birds too.

Saying that it could fly with the facts showing that its structure was not readily able to support it is not good science either. Perhaps you are getting flight and powered flight mixed up. Gliding is flight, and Archaeopteryx could clearly do that... however so can squirrels. But neither creature's structure supports powered flight in the same way that a modern bird does.

And if its flight abilities are based on the toss of a coin, how does this make your beliefs fact? You're arguing one side, I the other... but it's still the same coin.

Your science skills are lacking.

There is nothing artistic about these drawings, with the exception of color we can determine these characteristics in the pictures to be quite accurate.

Nature Magazine, Vol. 322, p677 Archaeopteryx, a star attraction "link" between reptile and bird has been refuted. Two crow sized birds 75 million years older than Archaeopteryx have been found... a paleontologist at Texas Tech University, who found the fossils, says they have advanced avian features. and tend to confirm what many paleontologist have long suspected, that Archaeopteryx is not on the direct line to modern birds.

News in science
"It appears that the early ancestors of modern birds lived lifestyles that today we would stereotype as being duck-like, heron-like, loon-like."
Spectacular 100-million-year-old fossils, complete with three-dimensional bones, feathers and foot webbing, suggest living birds evolved from waterfowl, say researchers.
News in Science - Scientists catch the early bird - 16/06/2006

Time will show that birds did not evolove from dinosaurs, but from other birds. And birds such as the Archaeopteryx will also be shown not to be a missing link between dinosaurs and modern birds.

Yes, but the clay figurines were made in a time when those dinosaures that they represent were suppose to be gone. Now unles those primative indians were involved in advanced dinosaur reconstruction, one would have a hard time explaining how they were able to make accurate figurines of dinosaurs that they had no knowledge of.

News in science is not a scientific journal.

The fact of the matter is the archeopteryx represents the transition from reptiles to birds and yes, it isn't the only or the first species to show this transition but it is one of the most well known examples of this. There are species that have a more balanced distribution of reptile and avian characteristics such as the Rahonavis (Rahonavis: Information from Answers.com)

Gansus is a genus of aquatic birds that lived during the Albian stage of the Early Cretaceous period (around 110 million years ago) in what is now Gansu province, western China. It is the oldest-known of the Ornithurae, the group which includes modern birds (Neornithes) and extinct related groups, such as Ichthyornithes and Hesperornithes.

Gansus - Wikipedia, the free encyclopedia

Ornithurae (meaning "bird tails" in Greek) is the name of a natural group of birds coined by Ernst Haeckel in 1866. Haeckel included in the group all "true birds" with the "characteristic tail morphology of all extant birds" (translation by Gauthier). This distinguishes the group from Archaeopteryx, which Haeckel placed in another new group called Sauriurae. Said simply, modern birds have short tails, while Archaeopteryx has a long tail like that of theropod dinosaurs.

Ornithurae - Wikipedia, the free encyclopedia

There also happens to be a forty million year hole between Archaeopteryx and Gansus. Archaeopteryx existed 150 million years ago... Gansus only 100.

Archaeopteryx existed 150 million years ago if you believe that, I don't. Yet a new discovery in a Dockum formation near Post Texas, by Sankar Chatterjee. Sankar found two crow sized birds that have been dated to 225 million years old. And these birds are more birdlike than Archaeopteryx. Thus Archaeopteryx couldn't be the ancestor of birds if a more modern type bird has been found, and is 75 million years older. I believe the name of these birds found is Protoavis.

Almost all paleontologists doubt that Protoavis is a bird.

Protoavis - Wikipedia, the free encyclopedia

Also of neatest note...

Sometimes it is claimed that Protoavis is a refutation of the hypothesis that birds evolved from dinosaurs. But this is not true; the only consequence would be to push back the point of divergence further back in time and possibly cause the dromaeosaurs to be included in the bird clade. Note that at the time when these claims were originally made, the affiliation of birds and maniraptoran theropods which today is well-supported and generally accepted by most ornithologists was much more contentious; most Mesozoic birds have only been discovered since then. Note also that Chatterjee himself has used Protoavis to support a close relationship between dinosaurs and birds.

You mean this thing?

How many modern birds do you know that have a tail like that? Or a mouth like that? Or claws on their wings? This bird is more similar to archeopteryx than any modern bird.

It is an extinct bird, and todays science states it has more modern features than Archaeopteryx. It's not a matter of them looking like Archaeopteryx, it is a question of them being more advanced than Archaeopteryx. And because they are much older, yet more advanced, science has ruled out Archaeopteryx as being a transional. If Archeopteryx was a transional, it would be going in the oppsite direction of Evolution. lol

You believe evolution has a "direction". It does not, at least not in your view of the concept. It tends towards the organisms best fitted for the environment, not the most complex or advanced. Remember, the whole thing is relative.

Science has not ruled out Archie as a transitional. Nor has it confirmed Proto as a bird. You're using blind faith instead of fact again.

Another bird discovery that refutes Archie. If Archie was the bird that was to be the transional that all other birds evoloved from. Why do we see another bird named Eoalulavis? It existed at the same time as Archaeopteryx, and this bird had no teeth, it had a beak, feathers, and a skeletal structure as modern birds. If birds existed already with the features as modern birds, why do you think they had to evolove from Archie?

Another new discovery of a fossil bird called Liaoningornis in northeastern China shows us a sparrow-size bird, and it possesses a keeled sternum which is seen in modern birds. It is said to be around 137 to 142 million years old.
I know you want to believe in evolution, yet why believe in evolution when it is obvious that the bird you have chossen for a transional is surrounded by birds that are already equipped with what we see in modern birds today?

I'm not useing blind faith, I'm just looking at what science has already discovered. And I have accepted their findings.
