The reason why Goa Magara is classifed as an ??? is because, its true nature was unknown until recently(It had some features belonging to both Elder Dragons and Wyvern species) and plus it lacked the ability to cause a natural disaster while other Elders were able to. Also Goa Magara's virus is not as deadly as Shagaru Magara's virus which can cause all species in an enviroment to go extinct.
