Is a terror bird a dragon?
According to modern science, birds evolved from bird-like raptors sometime in the Jurassic period.
It's been said often in recent years that birds are, in fact, dinosaurs, and that raptor dinosaurs have few, if any, traits that distinguish them from birds. However, orthodoxy dictates that birds evolved from only one species of raptor dinosaur, and that all the thousands of species of bird descend from the direct proto-bird ancestor of this same single species of raptor. It has even been shown that all raptors likely had feathers or at least proto-feathers, even the famous T-rex. Thas finally solved the riddle of why T-Rex arms are so small compared to the rest of its morphology; they are not arms at all but 'wings' used for balancing!
However, there has been much debate about which raptor is the direct ancestor of birds. What's more, there is no actual evidence that all birds evolved from a single species of raptor. The greatest argument for a "one-raptor origin" is that supposition that the development of flight likely occurred only once in avian evolution.
Considering how often scientistrely on "convergent evolution" to explain similar traits in species of different taxon, such a supposition is questionable at best. Wings used for gliding might easily evolve into wings used for flying more than once in the millions of years of raptor evolution, especially considering how quickly this ability arose in the evolution of insects, reptiles, and mammals.
However, it may indeed be the case that avian flight arose in only one species among the ancestors of modern flighted birds. That does not necessarily mean that all modern birds had an ancestor that could fly; in fact, there is no reason at all for this to be so.
According to wikipedia, "Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were the largest species of apex predators in South America during the Cenozoic, 62–2.5 million years (Ma) ago."
62 million years ago is the time period where fossils start showing up again in abundance on the planet after the K2 event, which supposedly destroyed the dinosaurs. This is supposedly only shortly after South America broke away from Africa.
For 10 million years before and after the proposed time of the K2 event, fossils become scarce over the entire planet. However, many animals that lived before and after K2 do not have any fossils from this "blank period" of our fossil record. Therefore, we know that just because we don't find a fossil of an animal between 80 million and 65 million years ago, it doesn't mean that the animal wasn't around. In fact scientists have found a refugium in North America where dinosaurs survived for at least several thousand years after the K2 event, and are likely to find more of these 'refugium" in years to come....
The existence of dragons, the reality of dragons, the dragons that were.
