How did birds evolve? How did feathers and flight appear? After a century of silence, these questions were raised again at the beginning of the 21st century when numerous species of beautifully preserved feathered dinosaur fossils were discovered in Liaoning, China.
By mixing images of fossils at the dig sites, ultra-realistic computer graphic reconstructions and interviews with paleontologists, The Mystery of the Feathered Dragons offers the viewer the opportunity to plunge into a modern scientific adventure. During this paleontological investigation, each new fossil helps to complete the puzzle of the transition from dinosaurs to birds and raises fresh questions. How did flight evolve in dinosaurs? Did they run along the ground to take off? Or did they glide from trees to land on their prey? Numerous parallel debates raged in the paleontological community until the discovery of Anchiornis huxleyi in 2009 - the missing link between dinosaurs and birds. More recently, in 2014, a completely new herbivorous dinosaur was dug up in Siberia showing that the presence of feathers went even further back in the dinosaur family tree. In fact, it’s possible that dinosaurs were feathered from the start of their appearance on Earth!

Just study a chicken. The rooster specifically. It's very easy to visualize a small raptor standing before you. If a rooster was as large as one of the medium sized carnivorous dinosaurs, there would be no doubt it descended from dinosaurs. In fact, roosters represent really ferocious raptors. They attack with their claws forward then, their beak goes in for the kill. Roosters can be exceptionally viscious & relentless. They can inflict serious injuries very quickly. Just imagine if they had teeth instead of a beak & a large sickle claw on each 3 toed foot, along with a long tail. Chickens are omnivorous & exactly like truly terrifying little pack hunting raptors!!!

Archie was primarily a ground-dweller in an arid environment with few trees - documentary has problems in this respect - and their feet probably were not suited for sitting on tree branches - it is more likely they were very poor flyers as their anatomy strongly suggests, and basically ran along the ground while making short spurts of powered flight (to escape predators, for example)

Someone who actually has a brain and uses it... wow I am very impressed, you don't see many people questioning all their lies propaganda and stupid assumptions. Great job

technically, YES, most dino's have feathers - because since the end of the Mesozoic, there are just alone TODAY some 9,000 bird species - and over the past 64 million years there were many others, now extinct - DURING the Mesozoic, no - only the Coelurosauria developed feathers, and even among them, some did not - large tyrannosaurs, for the most part, for example - vastly outnumbered by the quantity of species of other completely-scaly dinosaurs

Ok, done watching. But how do you explain that birds came from dinosaurs when you have the proposed feathered dinosaurs that are supposed tl be the ancestors of modern birds placed at as many as 120 million years after the fully formed and fully feathered bird Archeopteryx? How do you evolve into something that already exists? How come there are no documented cases of anyone finding fossils of feathered non-avian dinosaurs until after the theory of a missing link between birds & dinosaurs had already been accepted by mainstream paleontology (Sinosauropteryx, China 1996)? Archeopteryx has a clearly bird skeleton with a bird's tail and its balance point at the knees whereas Sinosauropteryx has a clearly dinosaur skeleton with it balanve point at the hips - if a bird like Archeopteryx (which, as all birds do, must walk from the knees which afe tucked into the body) tried to walk like a dinosaur from the hips it woulf fall over unto its beak. Seeing as how more than 30 out of 60 known "feathered dinosaur" species come from the same place in the Yixian formation in Liaoning China, with the recent case of the confirmed "feathered hoax" of the forgery behind the fraudalent Archeoraptor in mind aftrr being presented as an official "missing link" between dinosaurs & birds makes me wonder how many of these fossils are being checked for validity before their publications. A lot of the papers don't say if the fossils were excavated or simply bought - local farmers caught unto the fossil craze real quick and began selling fossils of their own to scientists eager to make a name for themselves on some article. "Paleontologists have tried to turn Archeopeteryx into an earth-bound, feathered dinosaur. But its not. It is a bird, a perching bird. And no amount of 'paelobable' is going to change that". Alan Feduccia, Paleornithologist
