The taxonomy of Dragons is difficult, much gaps have to be filled with guesswork, fossils are rare and often in bad condition. This updated cladogram is smaller than my last one, but much more up to date and also include recently discovered genera.

Forgive me for asking as im sure you get this alot and have probably already answered it numerous times, but what are your dragons closest modern ancestors again? Or what known animals extant or extinct are they derived from?
Hyrotrioskjan's avatar
Monitor lizards are the closest living relatives, actually they are dragons.

I can't see iberotaurus in this diagram. :l
Hyrotrioskjan's avatar
I'm not sure if I will keep this species and if which position it will have in this cladogramm (maybe near the Orientalosauridae) and it would be a extinct species.
DesOrages's avatar
Ah I always liked Iberotaurus. :( What about Datoupterus then?
Hyrotrioskjan's avatar
Can be found at the wyverns =)
DesOrages's avatar
Oh yeah, my bad. :)
DesOrages's avatar
Or Datoupterus. Hmmm...

How many families are their within Draconidea?
Hyrotrioskjan's avatar
12, but this number is matter of long discussions because not all are sure if some of these single genera families really exist or if they should be included into this or that family. But these are just human constructs...
DesOrages's avatar
12! That's more than I thought. So are the families something like: Wyvernidae, lophoraptoridae and... that's all I know.
Hyrotrioskjan's avatar
Not all have a name yet: Cryodraconidae, Unguladraconidae, Insuladraconidae, Corytholuridae, Orinetalosauridae, Volatiosuchidae...
DesOrages's avatar
So quite a diverse range then. Also is draconidae a family or superfamily?
Hyrotrioskjan's avatar
Difficult to say, the varanoid cladistic is a mess, and I normally like to use terms like taxon and clade instead of these hierarchic taxonomic words =)

I will need to find official terms for the literature but in the moment I try to avoid such specific infos.
DesOrages's avatar
OK, only because I assumed the groups within the update cladogram were families and draconidea was a superfamily containing them.
Hyrotrioskjan's avatar
Indeed, but the Varanoidea are also a superfamily ;)

So within the family Varanidae, we have some lizards, most of which seem to be extinct, and dragons which lost their wings and created monitors? Is that right? So it's something like Lizard->Dragon->Lizard?
Hyrotrioskjan's avatar
More like: Lizard->primitive Dragon->Monitor lizard, but yes mostly right.
TheLOAD's avatar
That's really cool. I love secondary flightless animals.

Dude I admire your work! These works of your are truly amazing and inspirational! It takes true talent, skill and knowledge of evolution and animal anatomy to create such art!
I have been thinking of making dragons of my own already a long time. You see I too have been thinking of what if evolution had done this or this? Difference in my dragons will be that they'll be feathered :)
I'll let you know when my first dragon work is done, if you have time to sacrifice in such things.
Hyrotrioskjan's avatar
Yes, send me a not :lol: I could imagine that primitive birds like Enantiornithes is a base model for such dragons.

Dear God... now I remember why I didn't pay much attention in the caladistics lecture I attended, it makes my head hurt! Seriously though, great job :) It's getting harder and harder to remember these are imaginary animals.

Thank you so much :hug:
