L Shaped Heliophyllum Horn Coral

This small horn coral demonstrates the rough events that can occur on the sea floor.  The Heliophyllum coral started growing up toward the feeder currents and it was then pushed over.  Not being deterred by its horizontal predicament the coral rotated about 90 degrees and started growing toward the feeder currents again.

Coral was found in Jeffersonville limestone of Clark County, Indiana which formed during the Devonian period.
