In the same vein as Wings of Nope.
Listed are various styles of some kind of deinonychosaur.
Almost all animals portrayed in this chart can happen for one reason or another naturally. Naked faced and naked head and necked dinosaurs occur now, and would've likely done so in the past as well. The Nopes are more of a 'this is not how ALL deinonychosaurs looked', which some people seem to actually think,for one reason or another. Variation happens and, even within the same genus, it's possible to have wildly different feathers or baldness(On the head and neck).
In the first row, the first listed is the template for the rest. It is completely naked. This is how the media (JP) portrays their raptors.
yes, the raptors in JP are naked, NOT scaly.
Here we have a list of peculiar stereotypical raptors, from those who may have used a skeleton as a reference, but didn't research integument(body covering).
The first one is a very very common occurance, it is known as 'shrink-wrapping' and is usually played off as 'i did my research' as far as the shape of the skull goes(this is often not the case however), OR is used to just give extra detail to the skin. The real animal wouldn't likely have the holes in the skull showing extensively, unless they were starved to death. Some people even make the holes in the skull show THROUGH the feathers, that's crazy!
The second is the JP3 or Talon(from Primal Rage) style, where the raptor has a few feathers stuck to the top of it's head, maybe a couple on the arms and tail too. This is the equivalent, in raptors, as having full blown and horrific mange.
The first two may also be drawn by people who 'don't believe' in feathered dinosaurs, often equating them with chickens.. despite there being many many cool and badass avian dinosaurs around today, like the harpy eagle!
The third image is what is commonly seen in what people call'half-bird' dinosaurs like archeopteryx. They don't see birds but as weird feathery lizards, and this style reflects that. Some dinosaurs may have actually had naked heads, for a variety of reasons, however, much like vultures or turkies do.
Fourth is about the same as the third
This row are styles commonly used by artists that know how to feather the dinosaurs in a plausible and reasonable way.
There's actually not much to say on them, and the possibilities are nearly endless, especially depending on style.
The major fluff and 'go crazy' row. These are all fairly plausible in some line of deinonychosaur and is seen in modern day avians
The first imagine is a raptor with owl-like feathers
The second is one with thin whisker-like feathers and eyebrow crests
the third is one whose feathers form a shape like that of a pigeon.
This row has seemingly infinite possibilities and is the most fun.
