What is the smallest/minimum size for a Amphiplaga Brachyptera found in the green river formation?

I recently made a trip to Kemmerer and found a amphiplaga brachyptera which is a just around half an inch, (just smaller then a penny and just bigger then a dime). It led me to ask what is the smallest specimen found, and how small are fry usually? Google doesn't have many answers, maybe because it's a rare fish and (not fully sure) was a relatively new classification. Any answers would be great, and I'll add the photos.

This is not an Amphiplaga but a Mioplosus. There are two dorsal fins.

Dang... I see it so clearly now I just trusted the head of my schools geology/fossil museum. I'm still curious about how small they got though any ideas?

This can happen to anyone. I have just looked at my specimens of "Amphiplaga" again and discovered that I have also misclassified a fish as Amphiplaga (instead of Knightia).

To answer the size question, I would think a few millimeters would be the smallest fry that could be seen/found.

when I think about other sites it was not possible to see fishes with less of 5 mm... 

Never seen Fishes from Wyoming below the shown one, really a tiny one
