@Democide Many wyverns in general especially the bipedal ones share many traits with birds. I believe that like dinosaurs wyverns in MH have an ancestry with birds as this can definitely be seen with Bird Wyverns especially Hypnocatrice and Qurupeco. Also if you look at Rathian, Berukyurosu, and Doragyurosu on their backs and necks you'll see patches of what may look like fuzzy patches of fur is most likely a form of protofeathers. Wyverns the bipedal ones have the same hip structure as birds and many shared behaviors and attributes. This is why it makes sense to me that Wyverns and Bird Wyverns are in the order of Saurischia in the Hunter's Encyclopedia books. Wyverns are at most distantly related to dinosaurs but branched off and became their own individual species, yet like the dinosaurs they are in close relation to birds. Also Gargwa are listed as Bird Wyverns yet they are truly birds. Gargwa obviously evolved from a species of wyvern to be classified as such.
