Damn, dinosaurs didn't evolve like that XD

I think that Dara, Garara and Raviente fit in the same group which is part of the Leviathan Family. Dara evolved a more real-snake snout, while Garara and Raviente got a more crocodile-like mouth, and both got tusks (Garara got also a beak, which uses to dig I suppose). Raviente lost the typicall thorax of other Leviathans, much like real Snakes. But it still got the arms (those "fins" behind the head, I think they have evolved from arms).

Lao Shan e Fatalis fit in another group IMHO, they are more related with other Elder Dragons (Kushala, Chamelos etc...).
