Unknown Horn Corals Found in Louisville Kentucky

Here is a grayish rock found in Louisville Kentucky that is possibly Louisville Limestone. What find appealing to the largest of the horn corals in the rock are the layers (growth?) that appear along the horn. Not sure if these are Devonian or Silurian. The matrix they are in contains a number of crinoid stem pieces and maybe a spine or two.
