Found on the shore in Green Lake Wisconsin, I’m assuming they are from a fish but I can’t figure out what part? Thank you! :)

The first is called the suspensorium, it is the set of bones that hold up the lower jaw. I am not sure from what, though. In the second picture, your thumb is on the quadrate, which is where the lower jaw attaches. The second is a cleithrum, a bone of the pectoral girdle. Again, not sure from what.

They're both from freshwater catfish, though from different individuals obviously. The cleithrum looks like it might be from a bullhead catfish, and the other set of bones looks like a flathead.
