Identification Help

Does anyone know what these are. I think they might be fish scales, but I'm not too entirely sure. We found them by the river; the big one is about 2in tall, the other is 1in. They have a somewhat bony texture.


  1. Those are opercles (the bone that covers the gills); what river did you find them in? They appear to be 2 different species and likely belong to minnows or suckers

  2. Ah, thanks for identifying. They were found by the Rock River in Illinois.
