` ::The lead already says the first description of it's external appearance appeared in 2012. Perhaps I could add ``published`` in there somewhere to make it clear. Still not sure how to reread what you were referring to above:   ``Until 2012, nothing was known about this species other than cranial and dental anatomy.``  Again, to be clear, we could add ``published about its external appearance``? Or is that too wordy? Or maybe reword the sentence altogether. What do you think?   `
