Description
The Near Bird, Anchiornis huxleyi. First thought to be an avialan close to Archaeopteryx, now known to be a troodontid with Microraptor-like feathers, proving that all deinonychosaurs and possibly all birds evolved from a four-winged body plan.Anchiornis is extra weird to the the complete feathering of the foot, like a modern Ptarmigan. In a future, more refined digipainting I'll try to emphasize its other notable feature--its minuscule size. Anchiornis was 34 cm long including tail and about 110 grams in weight, as an adult, making it the smallest dinosaur in overall size. Epidexipteryx is shorter but only because it lacks a long skeletal tail.
Oh, and it's from a few million years before Archaeopteryx, and it's even earlier than Epidexipteryx/Pedopenna/et al. But it's not the first bird because people don't like their Velociraptors being called birds, and yes that's the only reason

This one could still be a female...

To be fair, they only tested on specimen with the colour detecting method. As far as I am concerned some populations, or even the entire opposite gender from the one of that individual, could have been coloured like this

As an important note- They recently released a study on the actual colouration for this dino. It kinda looks like a woodpecker.

Yup, very exciting stuff! I've since done a new version with the proper colors: [link]

WTF is this animal Anchiornix huxleyi!
I don't really get it why their legs are also 'wings'. Heck, they aren't wings, wings are limbs or appendages that allow for flight, and these animals didn't really 'fly'. So why call them wings?

To simply everything, the "leg wings" were simply used as modern birds use the tail feathers, ence their use. Indeed, at least a few enantiornithes had leg feathers like Microraptor and Anchiornis, given that they generally lacked complex tail feathers as in modern birds.
And Microraptor had a better flying apparatus than Archeopteryx; given that Archeo had asymmetrical wing feathers, it did used flapped flight, so...

Gliders use wings too... And they (or their close ancestors) almost certainly glided.
Ostriches don't fly, would you say they don't have wings? What do you call their arms?

Arms! Arms with feathers! Hahahaha!
It's really hard for me to imagine these animals flying. Maybe jumping like a chicken, but...they're just not built for it.

Have you seen programs like this Nova special? ([link] ) Or read any of the papers studying the aerodynamics of basal eumaniraptorans? Microraptor even has asymmetrical wing feathers. The only reason for such a configuration to evolve is flying or gliding.
What do you think such large wings were used for if not flight?
In my opinion, dinosaurs like Caudipteryx with puny wings were certainly not flying but basal troodontids, dromaeosaurids, etc. certainly were. It takes some very special pleading to try to argue against the fact that dromies and troodonts are flightless or glideless birds when their ancestors all had extremely long "arms" and huge wings made of modern flight feathers on both sets of limbs!

That program looked like BS to me. It's kind of hard to imitate real life, really, and Microraptor (or any of those dinosaurs) can't spread their legs outwards like that (the whole tent like position thing looked kind of...dumb) I dunno. I do believe they could have glided around, but with lots of reservation.

You'd say the same thing about Archaeopteryx then, right? Microraptor's flight apparatus is more advanced.

Can Archaeopteryx truly fly?

Subject of debate, but certainly not as well as Microraptor.

You are really good at coming up with realistic looking patterns for feathered dinosaurs that look adequately birdlike without copying an existing bird. Nice job.

Aw but yours had a nice top-down view! Had to really resist the urge to do a dorsal, wing-spread view to show off wing anatomy, but will do that one next
