That picture makes me want to have this in an RP. I love dinosaurs too, even if I know very little about them. I've NEVER seen them in a fantasy setting before in any RP...yet, like some have said, (including you Jannah :P) fantasy has a lot of dragons so why tf not? Dragons are common yet not so much with our Saurian friends. I'd love to see this more often in RPs, it could lead to some very interesting things.

On a note about being very careful with them, why? Since when does RPing have to exactly duplicate stuff IRL? If someone *wants* a desert dino in a jungle environment for their RP, what's the problem with it? It's RP, it's fiction, and I don't think one should limit themselves to something just because it's not "realistic." Neither are elves shooting fireballs from their hands or dragons swooping down from the sky enveloping an entire city in a rain of fire, but it's done. I say cut the RPs some slack, it's supposed to be fun :)
