Fossil forum, 

I have just finished uncovering a gnathasome fish scale. It is from the Leighton Fm, Maine. I believe it to be in the genus Gomphoncus, maybe even Gomphoncus sandelenis, which was described as being in the Eastport Formation (https://www.erudit.org/fr/revues/ageo/2018-v54-ageo04224/1055415ar.pdf). I am unsure of this id though, mainly because of the pit in the largest end of the scale. It is approximately 200 microns long by 250 microns wide by 200 microns deep. Any help on the id of the genus, or maybe even the species, would be greatly appreciated. Here are some pictures of it:

The more I learn, the more I find that I know nothing.
