Talk:Gojira57's Monster Hunter Monster Evolution theory/@comment-25043807-20150227011625

Brute Wyverns would just really be large Theropod Bird Wyverns and true Bird Wyverns would be birds that evolved to be similar to wyverns.

Leviathans would be a wastebasket taxon as some are Crocodilian, Amphibious, and fish like.

Piscine Wyverns could be hyper evolved lobe finned fish.

Fanged wyverns are like therapsids or mammal like reptiles to me.
