From how long this wyvern's back legs are I'm thinking about the extinct wyvern, Canpous. This new wyvern's back legs are longer than most other Pseudowyverns I've seen plus its still able to use them like Bipedal Flying Wyverns, atleast telling from the way it was using them to attack Rathian. So I think its possible that it doesn't completely walk and fight on all fours but may also fight and walk on two legs. This is just my theory on this wyvern.
