i think flying wyverns might have evolved from fishes. just take a look plesioth, it's like an underwater rathian! maybe a plesioth learnt to fly with his enourmous fins and thus abandoned the sea, adapting his skin for on-land life with rougher scales. the similarity between plesioth and rathian might be just an evolutive coincidence though.
