Has anyone found a Wyvern yet?

I have got the orange an the purple so far, but I agree with @Pawz ; like that they were put in but disappointed that they only put in the weak version though.... I got 49% taming chance with full life.. will say freaking taking 2 on an taming is painful seemed the orange poison/hits were doing a lot more damage then the purple was though for some reason soloing the purple was nothing used to dot heals an only needed healing touch 2 times on 3 taming attempts.
