Rostroconch Imprint - Louisville, Kentucky

I think these are imprints of rostroconch creatures in Jeffersonville Limestone found in Louisville, Kentucky. The white material might be what is left of their shells or part of the material that made the mode. I found two pieces next to each other but they do not seem to fit together. A heavy piece of earth moving machinery crushed this rock so it is hard to say what it fully looked like.

The rostroconch I have seen found in this area are called Hippocardia cuneus (Conrad, 1840).

Unknown Devonian Horn Coral

I am not sure what this horn coral is called. This one has 43 septa and must have been deformed into an elliptical shape. This horn coral was found in Louisville, Kentucky in maybe the Jeffersonville and Louisville Limestone.

The outside has beekite patterns.

Genus Heliophyllum Devonian Horn Coral

Here are some pictures of a Heliophyllum horn coral of unknown species from the Devonian period. I make the identification as Heliophyllum because it was found in Louisville, Kentucky in the Jeffersonville Limestone and the septa have small beads or teeth along the line.

The images go from a close up of the lines to further out of the coral fragment.
