fish fin?

[Bonehunter]

Been cleaning conodonts when I came across this in Pennsylvanian Stark Shale member between Winterset and Bethany Falls limestone in Kansas City. took me almost as long to get the lighting and focus in perspective as it did to clean it!. Is it reasonable to say this is a fin rather than a scale?......and any thoughts on taxa or even species?  As usual, thanks all!!      Bone

Looks like an operculum from a fish, yeah. No idea about the taxon.

Not a fin, not an operculum. This is a bone of the face, probably a dermosphenotic. Couldn't give you an ID offhand, but you could probably pull up a species list for the Stark Shale or the equivalent Mecca Shale of Illinois and do some side-by-side comparisons and narrow your ID down credibly to genus or even species.
