Maybe Elder Dragon is a class because they were once believed to be mythical. Chameleos in MHFU is rarely seen. Ceadeus in Tri recently discovered. Maybe Elder is just another way of saying the monsters are or once believed to be legends/myths as well as not fitting into any other category due to lack of information about them. Dara could fit into snake wyverns. Kirin maybe in the same family as Kelbi but since it's unlike any other herbivore in game it's got a legendary status thus becoming an elder dragon.
