Fish fossil help!

I found a REAL BARGAIN online... but not identified.  I am thinking Diplomystus sp. ???   :dinosmile:

What are the diagnostic features of this Genus?  The odd mouth I have seen on Diplomystus  - but also on Knightea!

At a glance, I believe Knightia based on: apparent size, the odds (most abundant fish), and no indication of the ribbon-like anal fin, diagnostic of Diplo. Of course that is the very area of the fossil with the poorest preservation, so there is that factor.

Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See

I believe this is a juvenile Diplomystus dentatus, based on the features noted on this photo.

Thank you all!  I was leaning toward Diplomystus, but I ALSO thought Knightea was a real possibility!
