IMPORTANT! - This deviation is not currently up to date. I will update it with the new information when I have more time.

So I got both bored and inspired a few months ago and decided to go ahead and put this little bit of work together. I did a buttload of research online and couldn't find a single reasonably well-though out taxonomical list that featured mythical animals like dragon, phoenixes, anthros, etc. J.R.R. Tolkien constructed one, but it had a real weak taxonomy tree, consisting of only two branches and only including dragons (This one can be found here). Various questions on Yahoo! Answers include somewhat reasonable trees ("What would the scientific classification for a 'dragon' be?"). Another one I found had a little more flesh on its bone, including the class Xenosauria, which is also used in this taxonomy tree. It had a reasonable amount of influence over this tree, but unfortunately, I cannot seem to find it at the moment as I have used three different computers since then, but I will be sure update these author's comments with the link once I find it. Another good resource, which I found just recently, is a 38-page online document called The Evolution and Classification of the Dragon. Unfortunately, it doesn't appear to place the official dragon taxonomical rank further than Family.
This one, however, reaches much further back and includes more mythical creatures than just dragon. I do realize that this tree is nowhere near even beginning, but it's a start and can still be used efficiently to anyone who needs the scientific term for a dragon or other mythical creature they have created (such terms can be added upon request if they do not currently appear here).

  • Basilisks
  • Nagas
  • Mermaids
  • Centaurs

When you make request for the taxonomy of an unlisted creature, please include a picture to use as a reference for my convenience, as there are literally tens or even hundreds of different species for certain mythological creatures.

  1. 2.1.11 - I removed all the real-life animals except humans. Mustela glacies is not real animal, though they are very closely related to Mustela nivalis. Remember that some of these are my own creations. You might expect drawings of these sometimes in the future, but probably not the near future.

CHANGES: (In chronological order)
  • New Species
    • Caeluserpens pyrkagiás (Asian Fire Dragon)
    • Bipeda wyvere (Wyverns)
    • Anticuus fulmen (Thunderbirds)
    • Pennalus pegasus (Pegasi)
    • Ceri unicornu (Unicorns)
    • Gryphi ecus (Hippogryphs)
    • Gryphi pythos (Snake-Tailed Gryphons)
    • Gryphi ornis (Lion Gryphons)
  • Moved Species
    • Homo elementum lycans (Werecreatures)

Add a Comment:
First off I just want to say you did an awesome job with this; the level of detail and thought put into it are pretty amazing, and you took it way farther than most people would bother. However, I do have some suggestions as to how to divide your dragons based on biological features.

When you look at the typical dragon (excluding wyverns) they have four legs and two wings, for a total of six limbs. Every vertebrate in real life only has four. Perhaps you could make a split somewhere dividing the six-limbed creatures from the four-limbed ones. Probably the most sensible level is the order, although that would mean an awful lot of revisions :/

I also noticed you separated "scaled" dragons from "warm" dragons, placing feathered and furry dragons in the latter. However, feathers and scales are much more closely related than fur and feathers. Fur, horns, and hooves are formed of alpha keratin, while feathers and scales are made of beta keratin, which is much stronger. Also the same cells that make feathers in birds are only mildly tweaked to make the scales on their legs, so they are structurally more similar than feathers and fur. Then again, feathers and fur are closely related in that they grow in the deeper layers of the skin, whereas most reptile scales are formed on the epidermis. There are some scales that are formed in the dermis such as fish scales and the armor plating of alligators and crocodiles. I'm not sure if all that information makes you want to reconsider how you've divided furry/feathered and scaled dragons, but it's something to think about I guess XD

Another possible characteristic to divide your dragons up by is whether they are "warm-blooded" or "cold-blooded". I don't know if the order Calidrago was meant to include all the warm-blooded ones while the cold-blooded ones fell into Squamdraco, but you may wish to consider the dragon's habitat when placing it in those categories. Do all of the Squamdraco dragons live in climates that are warm enough so that they don't need to generate their own heat? You've placed the Tetrapa glaciictum in the cold-blooded category, but if it lives somewhere like the arctic (given that it breaths ice and all) where will it get the heat it needs to live? Is the dragon's habitat rich enough in food so that regulating their own temperature is actually more advantageous than sitting around and waiting for sunny weather? If it lives somewhere like the desert, then it can rely on the constant heat to keep it going and not waste calories on needless heating or cooling, but if it lives somewhere like a forest perhaps it could hunt more often if it was independent from the heat. These are all things to consider.

Unfortunately I don't know enough about your dragons species to offer much more advice. So much of it depends on where they live, what they eat, and etc. It is also very late at night and I can't remember half of the points I was going to make XD. I do recommend you consider the thing about four or six limbs, as well as hip and clavicle structure. Those two bone groups very immensely between various animals and each type has its pro's and con's. For example, big cats have minimal collar bones that are only attached to muscle, allowing them to land with great force on their front legs without breaking anything (or something like that XD). Birds, however, have crazy-complex chest systems involving an extra set of clavicle-like bones and a majorly-tweaked sternum to anchor the massive flight muscles they need. Feet too are another thing to think about. Do some of the the dragons have paw-type feet ideal for running, or do they have bird/reptile feet for totally different purposes? What kind of skulls do they have? Reptile and mammal jaw musculature differs greatly. Dental arrangement is a big one too- think of alligator teeth vs. dog/wolf teeth. Oh boy, I'd better quit while I'm ahead.

I apologize for my late-night rambling, but those are a few things to think about when assigning your creatures their respective titles.

As far as the layout itself goes, I would assign each level its own symbol; I had to keep scrolling back up to the nearest phylum to see what level I was on XD
What do you think?

Pretty awesome! I, personally, am a dracoligist with a PHD in the study of Dragonology and related subjects. Recently I have started a complete taxonomy classification of every single dragon species and breed ever to come into human media. Ever. [this may take time.] I was taking a break [because you can only do so many latin names before your brain starts melting] and googled "Dragon Taxonomy". . . really, you wouldn't believe the trash I found. Many people left out pseudodragons or variants other than the main western group. Your's, though . . . top notch work. You really didn't leave anything out. It's nice to know that there are other scholars out there who appreciate the careful study of dragonkind as much as me.

Holy CRAP this is amazing! I was looking for stuff like this to help me with my own made up species! Superb my man (or gal).
Lycanic Featured By Owner Nov 15, 2011  Hobbyist Traditional Artist
I love this work! It is so neat and awesome!

I wish you will add [link] fire elemental, water elemental, earth elemental ,wind elemental. And it would be better if "elementum" is a genus because they don't share common characteristics with humans and anthros (my own oppinion XD).
dehydromon Featured By Owner Feb 20, 2012  Hobbyist Digital Artist
Actually, "elementum" was a species created for my book and basically describes a human that has been endowed with one of the 21 elements. There is a slight change of DNA when that happens, thus turning them into an "elemental" as I see them.
I'm sorry to say that the elementals in your link wouldn't really fit into the taxonomy anywhere as they appear to me more divine beings (ie. a volcano god) rather than a biological organism. Sorry. ^^;
Lycanic Featured By Owner Feb 23, 2012  Hobbyist Traditional Artist
I understand. :)
daughterofbastet Featured By Owner Sep 3, 2011
:blahblah: You forgot Vertebrata, which should come after Chordata. Chordates have spinal cords; vertebrates have actual backbones. You also need Tetrapoda, which is what birds, reptiles, mammals and amphibians are part of. For humans, you didn't mention our tribe (Hominini) and you misspelled the family. There are some other things, like our superfamily (Hominoidea), our parvorder (Catarrhini), and our infraorder (Anthropoidea or Simiiformes). Maybe you should add Eutheria under Mammalia, too. These are important, it's not just nitpicking. :p I bet you can find half of this on Wikipedia, or even just Google. And if you don't do what they say, the rabid, foaming-at-the-mouth taxonomists at the Willi Hennig Society will come for you in the night. :fear:
ShroomDragon Featured By Owner Edited Mar 9, 2016  Hobbyist Artist
[just really quick . . . ] True. Drives me CRAZY when people do that AH MAH GAHAWAD  . . . but that's just me. Vertebrata is technically a subphylum of Chordata, therefore is not required when listing basic taxonomy overviews. Same thing with super- and infra- classification levels.
dehydromon Featured By Owner Mar 7, 2012  Hobbyist Digital Artist
I do realize there are quite a few I left out, but I only did so to save space. If I include every clade, I would end up with some 20 bullets leading down to an organism. If people were really interested in already-existing taxonomical classifications, they could just go check Wikipedia. On the other hand, people probably would be interested in the subtaxons of the mythical creatures, and I do admit that I should probably include many of them in this list. A lot of work still needs to go into this. Thanks for your input. :)

Common sense is not very common.
dehydromon Featured By Owner Feb 5, 2011  Hobbyist Digital Artist
No problem, but watch out for revisions. They'll be pretty common this early in the taxonomy's lifespan.
4kraft Featured By Owner Feb 4, 2011
Nice job, but what :iconrebeccannoying: said must be taken into account (what taxonomy doesn't need revisions?).
Anyway, griffons (or griffins) can't be part of Aves - it just can't happen for a bird to sprout all the hind parts of a mammal. They're 'chimeric' creautures in the sense it mixes two or more animals more drastically than a hybrid. I was working together with another person some time ago and we came up with the taxonomy of griffons, including ecology etc. :)
Also, werewolves (and the other were-stuff) can't be separate species. Lycanthropy is a curse (or blessing, depending on the werecreature's view), often placed on but sometimes born with, affecting cretures of different species, like humans, elves etc. They're regular humans (or elves etc) with some freakish ability.
dehydromon Featured By Owner Feb 9, 2011  Hobbyist Digital Artist
I figured that bit about Griffins. In fact, I had their current taxonomy under a 'Disputable' section at the very bottom of the list for a while. Taking your advice into account, I have moved Griffins to the class Miscera, which is, in essence, animal mixes. Chimeras, Basilisks, and more will soon also be in that class.
As for the werecreatures, I realize I forgot that there was a difference between them and anthros. Since they are able to change forms, I have moved them under the species pellicius, as the subspecies lycans.
Thanks for your critique. :)
4kraft Featured By Owner Feb 9, 2011
No problem. Glad I could help! =D
I'm a taxonomist myself, so I like to see things neatly arranged. :)
dehydromon Featured By Owner Feb 10, 2011  Hobbyist Digital Artist

I didn't make it up. A real life example is that domesticated dogs are actually a subspecies of grey wolves.

hmm there also seems to be Like>Domain>
dehydromon Featured By Owner Feb 2, 2011  Hobbyist Digital Artist

Actually, there's even more. If you include botany, there are 37 levels of classification. Most people only focus on the seven included above (and sometimes subspecies as the eighth).

Why are unicorns and pegasi not listed? And nagas. :/
And wheres the wyvern and basilisk?
dehydromon Featured By Owner Feb 1, 2011  Hobbyist Digital Artist
This list was originally created just for the creatures that would appear in my series, (with some extra dragons), so it didn't have a whole lot of other things. However, I will add those after a little bit of research.
