This hemispherical bryozoan might be a Prasapora simulatrix found in the Kope Formation of Carroll County, Kentucky. On one side of the bryozoan are borings that are trace fossils called Catellocaula vellata.
Thanks to Bill Heimbrock's Xfossil website entry by Dry Dredger's Ron Fine on the Catellocaula vallata (tunicate).
Last two pictures are top and bottom views of the bryozoan.
