It looks like a rather cute fluffy toy.
But, in fact, this is an artist's impression of a dinosaur that lived 160 million years ago.
Latest research suggests the crow-sized dinosaur Anchiornis had feathers on its four wings that fluffed up rather than lying flat like those of modern birds.
The primitive feathers may have actually hampered in its early attempts at flight.
They would probably have caused drag when the creature tried to glide between trees, say scientists.

>Modern computerized tomography (CT) scans of dinosaur chest cavities five years ago found the apparent remnants of complex, four-chambered hearts more like mammals and birds.
>Earlier this year, rare soft tissue of a T. rex showed its blood vessels were similar to those of an ostrich.
>Meanwhile, sketchy evidence in recent years had suggested dinosaur bones might contain air cavities. Still, some experts contended dinosaurs breathed more like crocodiles.
Interesting stuff. Thanks.
It might take them another 50 years, but eventually, they’ll admit that most Dinsouars were nothing more than big birds.
I beg to differ on the analysis of the article relative to the obvious poor aerodynamics of this “bird dinosaur.”
Today we have flightless birds adapted to their ecological niches. Emus do not fly but they can rip your guts out. They are flightless carnivores and well adapted to their environment on the ground and not the air. Emus are birds that do not fly. We also have birds of limited flight ability that are also perfectly adapted to their ecological niche. Wild Turkeys are a great example. They can fly quickly and explosive for a short distance. Their body weight prevents them from flying far and high. Penguins are bird that have great aerodynamic efficiency in the water. They do really do fly but it is in the water. 70 million years from now a paleontologist might look at its fossils and think this bird was an ecological dead end. In actuality it is a prime and successful predator in the Antarctica.
We have no idea what was the ecological niche for this “bird dinosaur.” This animal could be an evolutionary dead end or perfect for his environment. WE DO NOT KNOW! The paleontologist do not know either.
there are several recent ‘secular’ scientific studies that dispute the evolution of birds if you are itnerested in looking at them?
“Study challenges bird-from-dinosaur theory of evolution – was it the other way around? “
some studies suggest yet another ‘evolution’ from archeosaurs
“Birds DIDN’T evolve from ground-dwelling dinosaurs: Fossils reveal flying skills developed from tree-nesting archosaurs
“Are birds dinosaurs? New evidence muddies the picture”

As the article points out, birds are considered dinosaurs these days.
Oh goody ....more Fake Hostory
Yes, but there seem to be other opinions.
Yes it does. It’s a weird looking creature.
That is interesting. Thank you.
It looks similar to a sloth.

I can understand that view for the two legged dinos, but it wouldn’t apply to the four legged ones which were huge herbivores. ...JMO
You can have mine ...
You are INFINITELY kind! I think I’ll name her Soary. “Here, Soary!” She doesn’t bite, does she?
Absolutely brilliant connection!
Thanks. Odd looking critter.
Thank you. I majored in zoology as an undergrad, and have been a lifelong student of science, including a lot of field work. Critters R Us, if you will.
My Black Friday purchases should arrive today and tomorrow, new & much improved birding gear. Can hardly wait to get over this bronchitis and get out there to try it out! However, I don't expect to see a hoatzin around here :).
I think this is the original article that got me interested in the question:

What sort of gear? Sounds exciting.
I’m a backyard birder in MA. Spent one year standing at a window with a camera videotaping from a variety of feeders. The problem wasn’t the videotaping, it was the logging of a year’s worth of tapes. Bird 3 arrives; bird 2 leaves. Put a camera up on a series of upside down pots and stood on a ladder for an hour in a heatwave to get the first babies leaving a nest. The baby came out, flew to the top of the house and my battery died. !!!!!!!!!!!!! Two of the best scenes were one bird knocking another bird out of the air and a tiny bird making its way around a sleeping big bird in a clear plastic feeder in winter.
Looks like those suits those crazies wear jumping out of helicoptors and off cliffs.
