Summary

[edit]
Description

Fossiliferous limestone in the Mississippian of Kentucky, USA.

The Fort Payne Formation of southern Kentucky & Tennessee is a shale and limestone succession of Early Mississippian age. Fossils are common to abundant in many intervals. The unit is dominated by crinoids. Other marine fossils here include brachiopods, bryozoans, and corals.

The fossiliferous limestone slab seen here has numerous elongated, branching structures - these are auloporid corals. Auloporids are a group of extinct tabulate corals. They consist of calcareous colonies of hard substrate-encrusting, trumpet-shaped corallites. They first appear in the Ordovician and go extinct in the Permian.
