Yeah, I was assuming it was mottled brown all over. A sparkleraptor it be.

'Winged dragon' dinosaur discovered
http://www.bbc.co.uk/news/science-environment-33510288
"Scientists have discovered a winged dinosaur - an ancestor of the velociraptor - that they say was on the cusp of becoming a bird. The 6ft 6in (2m) creature was almost perfectly preserved in limestone, thanks to a volcanic eruption that had buried it in north-east China. And the 125-million year-old fossil suggests many other dinosaurs, including velociraptors, would have looked like 'big, fluffy killer birds'. But it is unlikely that it could fly."
What? Yes, my form of science fangirl geekery is more for prehistory rather than outer space. How did you guess?
Anyway, why don't more fantasy or sci-fi worlds have creatures like this? Just look at that picture.
...in my honest opinion, the restoration pictured below is, uhm, disappointing:
I mean, sure, there isn't any denying that Zhenyuanlong has feathers, but my main issue is the way the plumage is depicted, among a few other things. To explain, here's a dissection of the above picture, as taken from this Tumblr post on the matter:
The list of issues pointed out by the source post are as follows, in quote:
1.) Wing Structure. Whilst Zhenyuanlong had a complicated arrangement of primaries, secondaries, coverts, and retrices, here the feathers on the arm are represented as a simple fan.
2.) Pronation. Even though this isn’t Jurassic Park Velociraptor-like full on bendy wrist pronation, this posture is still unlikely and will cause wrist breakage.
3.) Leg Feathers. Here Zhenyuanlong is depicted with vestigial Microraptor-like hindlimb feathers, whereas the actual fossil lacks any feathers around the hindlimbs. This may be a taphonomic artifact, but speculation isn’t a good way to go for a reconstruction.
4.) Shrinkwrapping. It may be a matter of texturing, but the feet of Zhenyuanlong are horrendously wrinkled in this reconstruction. This is not that major a problem for the rest of the body.
5.) Posture. The right leg is bent at a crude, almost painful angle. This certainly calls into question how the hips of this thing even work.
6.) Coloration. Having this flashy coloration may not necessarily be the best choice for an active predator. On the other hand, this may be intended to be for display. In either case, however, the colour is not what we would expect for this animal.
To add to some specific points, and in concurrence to all of them:
* Like modern birds, deinonychosaurs had primary feathers attached to the second finger (look at the fossil of Microraptor, for example). Either the artist behind the restoration did not research the fossil find or I need new glasses, because I don't see any primaries on the second finger. The primaries are now common knowledge for a significant number of palaeo-artists on the Internet, as this comic wittily demonstrates. More seriously, the notion of large primary wing feathers and their supposed interference with forelimb function is discussed in depth here.
* Apparently, the shrink-wrapping as described in the Tumblr post applies only to the feet; in modern birds, the foot musculature is pretty minimal (I had fried chicken feet in Indonesia once, and they didn't have that much meat on them). I did notice that there isn't much padding in the right foot, however, so maybe that's why the feet look so awkward. A Dr. Scholl's sole cushion would've likely been necessary for a ground-dweller to support its weight, like in the feet of ostriches, for example.
* Regarding the feather colors: I think the paleo-art circles have an inside-joke term for color schemes like this: Sparkleraptors. From what I've heard, it's often garishly colored dinos like these that turn people off from the notion of feathered dinosaurs in the first place. As noted, it's also not a new thing, either - Archaeopteryx is always depicted as being colored like a tropical bird in old dinosaur books (which is especially jarring when all the other dinosaurs are elephant-gray, mud-brown, moss-green, etc.). Most meat-eating dinosaurs would likely go with more subdued color schemes as in modern predatory mammals, and vivid colors like a bird of paradise would probably be a seasonal thing for the sake of showing off to mates and such. For the technically minded, here's a detailed explanation on dinosaur feather colors, which should be helpful for portraying plausible color schemes for at least the feathered ones. (Note that Ripper's blood-red plumage is actually quite reasonable according to the article, since carnivores like him have only structural colors and melanin to work with.)
All that being said, the artwork itself is gorgeous once you get past the technical flaws (though I had to struggle to do that, being the palaeo-nerd I am). JP notwithstanding of course, feathered dinosaurs NEED to be a thing in modern prehistory media. And to those who say feathered dinos look stupid, go anger a goose and then we'll talk. XD
By Emily Willoughby
See? Far prettier. How's she done on that list?
1.) Wing Structure. This Zhenyuanlong has lovely complex wings. You can barely see the claws!
2.) Pronation. Those hands (what you can spot of them) are emphatically turned inwards, not downwards.
3.) Leg Feathers. Willoughby's Zhenyuanlong has feathered legs, but no fans - a more conservative reconstruction, allowing for preservation artefacts.
4.) Shrinkwrapping. What is there to shrink-wrap?
5.) Posture. It looks like a bird! She describes it as displaying at its reflection, hence the somewhat-fluffed-up wings.
6.) Coloration. One bright display crest (is that from the fossil? I can't see it, but both artists put it in), and then what I assume are browns, blacks, and whites? Definitely no sparkleraptor, this one.
Now why couldn't they have used a picture like that for the press release?
hS
If there's one thing wrong with it, it's that there's no sense of scale. The Zhenyuanlong just seems the size of a jay or magpie, rather than 6 feet long.
But apart from that, it is amazing. Thanks for that.
Even on pictures which have the most blatant scale-cues ever, such as trees, I find myself reading them as being small trees. That tiny thing below Dreadnoughtus is a 4m-long iguanodont, but I can't interpret it as anything above chicken size - thus under-reading Dreadnoughtus by a huge margin.
I don't know why. You'd think the size of trees, of all things, would be burned into our brains.
As for Ms Willoughby's Zhenyuanlong, I think I read it as cat-sized, which is actually pretty accurate (I'm not counting the tail); I spent every summer holiday of my childhood playing in a river with loaf-of-bread-sized boulders, so that's probably the reason. But magpie-sized is certainly equally valid! It's just what the rocks make you think of.
hS
You have no idea how much I LOVE Emily's work! She makes the best feathered dinos ever, and nothing will convince me otherwise! :D
And as a bit of a tangential plug, I'd also like to take the opportunity to promote one of my favorite dinosaur-related original fiction works: Palae Oh No. Basically, all the problems of human-era dinosaur media, retold with civilized, science-accurate dinosaurs and media about Permian synapsids instead. Palaeontology fans should definitely give it a read sometime!
Yes, I was dumb enough to make enemies with a rooster when I was a kid.
And you want to know a garishly colored bird that will really do you in?
Cassowaries, AKA the modern Deinonychus. These things have flarking stilettos built into their feet, and will not hesitate to disembowel you with them.
And these are the birds with the bright blue heads and ridiculous crests.
Which is, for the uninitiated:
In addition, they have a particular name among Aussie megafauna enthusiasts. That name? The DEMON-DUCK OF DOOM.
https://www.youtube.com/watch?v=bWYQ8ITitQo , because I just can't embed the video.
(This is from a French series on Youtube, referencing a previous one about Velociraptors: https://www.youtube.com/watch?v=SOfbNhHGIY0 )
Well, they may be wrong about the colouration - unless I'm colourblinding at it, the only bright colour is that crest, which could well be for display. That's not a full-on Sparkleraptor by any stretch.
But they're not wrong about the rest; that left foot in particular is just scary. And... I see it only has Microraptor feathers on one leg? Perhaps it IS diseased...
I do actually disagree about the quality of the art itself, though. It's... not all that good.
-The Zhenyuanlong suni doesn't seem to be part of the background.
-It's got its mouth open in that 'I am unlike any other predator ever because I roar all the time' post dinosaurs love to take (I love this image, which shows both predator and prey with their mouths shut, because running is more useful than screaming! [Source])
-Its feathers are, um, scratty. Do birds really have gaps between the ends of every feather? It seems pretty unlikely to me. And look at that throat - it's a mess! It's more of a mess than an urban pigeon, and that's saying something.
-The pose is pretty silly, with the wings stretching forward like that. It brings to mind a toddler racing across the room with her arms out to cuddle my leg (which is awkward when I'm trying to walk, but hardly fearsome).
I'm just... not all that impressed.
But I would dearly love to see a new Walking With Dinosaurs-style show featuring modern reconstructions. Feathered maniraptors, and bristly ceratopsians, and marvellously weird Deinocheirus and Spinosaurus, and superpredatory azhdarchids, and ridiculously wide-necked Apatosaurus and Brontosaurus, and... all the bizarre things that make the Mesozoic both stranger and more familiar than we ever imagined.
hS, whose only adventure in paleoart has been Celtic-knotted archosaur sketches
But then again, you're blue-green colorblind, right? The tail is basically a rainbow, red at the tip and going into green near where it meets the rest of the body.
I do dub this creature the Sparkleraptor.
Yeah, I was assuming it was mottled brown all over. A sparkleraptor it be.
hS
Would you have believed it before seeing it? Perhaps the writers felt that it would be too unbelievable?
Where are they getting them all? ^^
What does make me sad, both for poor Zhenyuanlong suni and for science journalism, is that picture. It just looks... scratty. Does Z. suni not know how to groom itself?
Also, it appears to be suffering from a horrible disease of the primaries. The fossil pretty clearly shows feathers running down at least one finger (as is the case for... every bird ever, I think?), but the art has the feathers stopping at the wrist in order to give it little clawed hands. Of... which the nearside one appears to be bent the wrong way, though that might just be the angle.
It's always cool to get another feathered dragon out of China, though. ^^ And the name-drop might even be vaguely right - V. mongoliensis is from that part of the world, after all.
('It is unlikely that it could fly'. Um, yeah, it's a couple of meters long, it'd need rather more radical wings than that to get airborne. But that's scientific journalism for you.)

Tyrannosaur teeth found in Nagasaki
http://www.bbc.co.uk/news/blogs-news-from-elsewhere-33522144
"Two fossilised dinosaur teeth found in southern Japan are the first evidence that huge tyrannosaurs once roamed the area, it's reported."
(Insert your own Godilla joke here.)
And we can do some art critiquing, too. The BBC is blocked at work, so I checked around the web, and found two different illustrations.
1/ Japan Times
This picture is designed to show of tyrannosaurs in general, not the new one in particular. It's immediately apparent that it's a compromise - one has fuss, the other has scales (heck, it practically has osteoderms). The fuzzy one has alarmingly-pronated wrists, and even the pebbly looks like she might have broken one. And, er, how many toes do tyrannosaurs have? Pebbly seems to have one less (the little one inside the ankle); is that meant to be present or not?
I also note with alarm that fuzzy's teeth are all the same, and that the two seem to have differently-facing eyes. And the colour schemes are a bit drab...
Basically, these are your bog-standard, jobbing-illustrator tyrannosaurs. They highlight the main features, repeat a few common mistakes, and then you forget about them.
2/ 2NewThings
This, on the other hand... this is what paleoart should be like.
The head is too large and misshapen, the legs are too skinny, the tail must be broken to do that, and none of it matters because the piece elegantly achieves its purpose:
-It shows the new tyrant as a Japanese creature, not a generic one.
-It shows that it was (almost certainly) feathered.
-It makes it look like a living creature, not micro-Godzilla.
-It's gorgeous and eye-catching.
Look at it! It doesn't even show the teeth, which are the only thing they found, and it's still a far better illustration of the story than the Generic Tyrants. Gorgeous.

That is beautiful. *freaks out*
