Paolumu's classification is unusual but we already have both Nargacuga and Barioth for mammalian wyverns so I'm sure they find a way to explain Pao.

Remember that many were dumbstruck by Jagras' classification too before SpaceJoker, MagicMonkey, I pointed out its relation to the synapsid Dimetrodon.
