Neither does it show the teaching of the Trinity or the Christological doctrines and yet you believe them, do you not? So let us not pretend that the protestant arrives at its belief and understanding of Divine Revelation solely from scripture.
Besides, doesn't sola scriptura (as opposed to solo scriptura ) allow for the development of doctrine? I mean, after all, that's what protestants tell me.
Those doctrines are indeed found in scripture.

Yes it does. All doctrines must be provable by scripture. Now prove the assumption and veneration of Mary from scripture and not some addition to scripture. Catholics, Mormons and Muslims start with scripture and add to it or change it.
