Psammodus? Fossil Tooth Plate

My cousin back from a recent field expedition found a large (5 cm) tooth-plate fossil. It appears to be a holocephalan known as Psammodus (Agassiz, 1834). The fossil dates to the Mississippian Period and was found in Grayson County, Kentucky USA.

 Thanks Kenny for the images.
