Fish mouth plate?

[Searcher78]

Thought this might be a tiny piece of a fish mouth plate.

What's the scale? I identified the somewhat similar-looking fragment below that I found in Aquia matrix as an Ostracion sp. dermal plate based on photos from @MarcoSr's website (the tick marks in my photos are millimeters).

The below page comes from the paper Weems  ADDITIONS TO THE BONY FISH FAUNA FROM THE EARLY EOCENE NANJEMOY FORMATION OF MARYLAND AND VIRGINIA (U.S.A) in the Mosasaur Volume XI June 2020.  Note, although the below figure is showing Eocene specimens, you can readily see the similarity of E and F to the Paleocene Aquia specimens in this post.
