Coenites verticillatus from the Louisville Limestone

I've shown you some specimens of Coenites that I collected from the Louisville Limestone in this past post. Today I have another species called Coenites verticillatus. It is distinguished from other species in that the diameter of the colony is much larger and it has a unique growth pattern.

As you can see from the above specimen, Coenites verticillatus seemed to grow on the periphery or sides of the coral reef. It would form a column like shape between a base and the lower surface of another coral. In the first picture you can see that the top of the column spread out once it contacted another surface. Thanks to Mike and Kenny for showing me the spot where I found this.
