I don't think we have. But if we were to assume that just because it can stand in a similar way to Miralis and Magdaros then it must have had wings in the past, then we should do the same thing for many monsters that, like Lao, have absolutely no reason to be considered as monsters that had wings in the past.

Kangaroos, when they are moving, have an appearance that «look like» the appearance of many theropods... And yet they have absolutely no relation with each other. That's why I don't consider the way Lao stands as a valuable argument on its eventual relation with Magdaros/Miralis.
