@Dippamus   Actually Pike is right Tigrex's relatives are indeed the baseline species of flying wyverns there is no such class as psuedo wyverns as that is a fan-made name of the quadrupedal wyverns. The creature that is the base of all flying wyverns is Wyvernrex, and said creature is featured in the Hunter's Encyclopedia G. Even in Tigrex's description it says "A flying wyvern that maintains its primitive origins". Also try not to be rude please.
