guys i just noticed...

the dragons we're fighting on skyrim...was it really a dragon??wouldn't dragon be a four legged mythical creature instead of two?

i once played Monster Hunterr,the two legged creature as we've seen on skyrim were called wyvern...

so is there any lore i've missed on this mythical creature should looked like??

It's a design decision, nothing more.

The lore basically is this; it's Bethesda's world Dragons could be 6ft tall with pink feathers and wearing a monocle if they wanted. If you over think it you end up arguing over who's imaginary creature is the "real" imaginary creature.
