General abundance:
Unknown
I have not examined enough nodules to determine abundance

Looks like a crossopterygian (lob finned fishes) scale.
It's tough to say more without more material, like some
skull plates. These scales look just like the one pictured.
Some are bony and show the porosity as in the photo.
We get similar scales in the Devonian here in the east.
