Have fun

Pterohippi are the modern development of my old species Equus avis. There is some more old species info here.
You can do what you want with them and develop them how you like.

This is a sci-fi/ science fantasy species concept, but I realised that the way I had taxonomically classed Equus aves as part of the Equus family is lowkey unrealistic, so here's an updated phylogeny tree for the species and, hence, a new clade name: pterohippus, derived from the greek ptero (wing) + hippus (horse), meaning winged horse, in line with the naming of some of the earlier horse ancestors like eohippus.

PHYLOGENY TREE
(caveat- I might change this as I do more research)

.............│ └── P. gracilis
.............└── Pelequus (membranous wings)
............... └── P. noctis
† = extinct

DOMESTICATION
Penequus gracilis is the one pictured above, on account of its feathered wings and slender frame. You are more than welcome to head canon your own pterohippus species if you want other builds or features!
If you want domesticated winged horses with huge variations in phenotype (like modern dogs and horses) you can tack the "docilis" modifier on to the end of the species name, (like the "caballus" in Equus ferus caballus or the "domestica" in Columba livia domestica). This lets you get away with big variations without having to make a whole new species for what you want.

In the lore I've written, pterohippi are extinct, but it's up to each player to decide the lore for their own world. Did science bring them back to life, or have some secluded populations survived in secret?

BREEDING
If you want to play "realism" then individuals in the batwing genus and featherwing genus probably shouldn't be able to interbreed, and breeding for fertile offspring should happen within species (e.g penequus gracilis x penequus gracilis, etc.).
However, if you want to push reality a little bit and allow breeding between pterohippi of different genuses or between pterohippi and regular horses or other fantasy species, then feel free to go ham, and you can make up your own science or magic as to how this happens if you want.

EVOLUTION
How the wings and horselike phenotype developed.
Pterohippi are pseudo-horses. They share a common ancestor with horses, but they are not really horses; they have different behaviours, vocalisations, and digestive physiology. For example, they use mammalian chirping vocalisations and hunt and eat small mammals, birds, and insects. They evolved alongside horses, competing with them for grazing but found additional success in hunting, due to an intestinal adaptation which allowed them to digest insect and animal proteins. Their flight capabilities allowed them to hunt in the forest dwelling stage of their evolution, and later to travel greater distances at lower energy cost, circumventing rugged or difficult terrain to seek out fresh pasture.

The last common ancestor that pterohippi have with modern horses is the eohippus. Aerohippus then emerged, evolving small proto-wings that aided flying-insect and bird hunting through rapid flapping for increased off-ground lift while leaping. At this time, aerohippus was still a forest forager like eohippus.

After this, divergence in wing development started to appear, with some populations evolving membranous wings, and some developing feathered wings. It is thought that membranous wings were advantageous in hot climates due to the surface area available for heat dissipation, and feathered wings in cold due to their insulation properties.

The Penequus is the feathered variant, its name deriving from the latin penna (feather) and equus (horse).
The Pelequus is the membranous variant, its name deriving from the latin pellis (skin) and Equus (horse).

FOLKLORE
"Horse that moves on the upper winds"
I'm still workshopping common names for the species.

Remember, all these species 'rules' and lore are just guidelines that I made up! You are more than welcome to use the species motif (the design of the species) for whatever lore or stories you want to.

I wanted to make a base in my art style now that I have one!

I don't like bases with lots of layers and options, so it's very simple, just what you see here

included inside the oekaki are the brush settings, and a tutorial of how to make a perfect white outline! Please let me know if I didn't explain it clearly :)

Rules:
Credit me if taken offsite!
Otherwise have fun, go wild >:3

Meowdy! It’s done… At least until I decide to randomly come back and add a bunch of stuff HAHA. I’ve seen very few non-skinny anthro bases here on CS, so I thought I’d fill the niche! Hoping that it can be useful for folks & I'm excited to see what people do with it ^w^
If you use this base, like it & want to see more variety added I encourage you to comment with suggestions for more options! 💖🐾

Features:

• 5 domestic dog heads
• 2 domestic cat heads
• big cat head
• rodent head
• bat head
• bear head
• fox head
• wolf head
• 2 bunny heads (upright and lop ears)
• deer head
• 2 snake/lizard heads
• fluffy raptor head
• 16 different tails (long, short, fluffy, scaly, fishy etc!)
• a few horn/antler/antenna options
• 3 distinct body types, with variations of each for flat chest or a bust, and varying fur lengths
• lock alpha color layers for almost everything!

• Please don’t remove my signature, though it’s alright to move it or change the opacity as long as it’s still visible at a glance!
• You can edit/Frankenstein/draw over the lines as much as you like ^_^
• You’re free to make paid adopts/custom designs on these lines, but please don’t redistribute the base for profit!
• If uploading colorins of this base on toyhouse, credit my side acc there @scrunkled :3

similar to but smaller than these from a year ago
again no signature, i dont care enough

credit me offsite as kageyenova if you want to give credit
idc what you do, just dont claim the lines as your own
gday

Each are 10 Retired Tokens or 20.C$ (3 Mimics and Familiars or Decor items from this last summer event, can replace each token)
I moved this to edits only for the purpose to make it easier for everyone else to take a look if any that they want, then announce here what cat(s) that they want and send the payment
Do not claim any of these or post any, unless you have purchased


EpicratesPictus still has to take a pick, as I was running this as a different way of adopting, but didn't get that far due to art requests as a payment...

After EpicratesPictus picks, they're all FCFS
The last 3 will be raffled, so try and not purchase everything left and leave 3 for raffles!

finally made a base i'm happy with!! pen settings are just the default (but with a bit of smoothing)

feel free to use for anything, be it pre-made characters, customs, adopts etc.. just don't claim the lines as your own or remove my signature <3
my toyhouse is @cherrycat if you need to credit there

It's a bit barebones, as I only spent 3 hours on it, but there's a decent amount of options to choose from! From fish to birds to lizards and mammals - mix and match the parts to your heart's content! I encourage you to move things around, edit the lines, even add your own parts! Go crazy! [Just be sure to credit me... ^v^]

You can credit me here, on Toyhouse, on Bsky... Just credit me as CrossbredManiac XP

Tail 2 pending but feel free to edit / color it in yourself

Four posing

Hey folks! happy new year <3

I recently felt inspired to hop back on oekaki and recreate my old cat editable. This is a remake of my original ultimate cat editable and version two. Somehow it’s already been 10 years since I released the original ?? ahhh where does the time go :’)

I do plan to add more edits over time, please feel free to suggest things you’d like to see!

There not done yet, but they are based off of the asmr squishy things. They also have a special juice inside of them that is edible to them. There stumaches are like pouches that are more squishiar then the rest of there body when pressed on just like the squishy products in real life. These pouches are clear and are able to carry a special liquid that I based off of a holloween candy called
Each one can do different things with this liquid.


Watermelon squishy (taken by my mom)
The nose, green parts of the watermelon, arms and legs are foam. Plastic seed's on muzzle. The face and belly are clear so you can see the watermelon juice inside of them. The clear parts are more of a gooey feeling instead of a foam like feeling. The paws and pawpads are extra squishy. They eat watermelons which is kind of why they are one.... the juice is stored in there stumache and increases there watermelon blood, while left over seeds from the watermelon is used to spit at people.
Also has a bite mark to show that they "bleed" watermelon juice.


Marbled jawbreaker laffy taffy cat (taken by my sibling cousin)

based off of a jaw breaker and laffy taffy. has little plastic balls that symbolise jawbreakers. Some are in it's body and the rest are in there paws. The jawbreaker is her bones. Has real candy in her earings 🍬. This candy makes jawbreakers which is what she keeps in her stumache. (Can only feel them when squished or slightly see them when pulled) can open mouth but only a certain amount sinse there body is stickyish. The shirt and earrings are made of wrappers. Based off a marbled cat. (Keeping, I'm sorry TTTT)

Bubblegum gumball
Based off of bubblegum squishy
Literuelly feels like bubblegum just not as sticky. Has a gooey yet thick kind of slower squish to it like gum. Can see special bubblegum juice in the face because it's a bit more clear too see it. You can also see gumballs in the stumache. Has gum tape as earrings so she/he/ they-them/it can shape there hair however they want to.

Not a species, just some designed.
Both belong to my siblings partner

Guess what im gonna do with this base. Bet u can't.

Comes with:
-separate layers for lineart and base
-4 species [equine, dragon, feline, canine]
-drag-and-drop lines for wings [bird and bat]
-every parent and kid is in its own group

You Can:
-edit the lineart however you want
-make adoptables (both free and not)
-use them for character references
-use them for challenges and contests

You Can't:
-claim the original lineart as your own
-re-post the transparent lineart+base off-site
-hide or delete my signature (you can move it, but keep it legible)


!!The wings lines are only for one side, if you want wings on both sides (or just want multiple wings) you can duplicate the layer you want (ctrl+shift+d) and move it behind the base!!

free to use, no rules, have fun!
