New calcimicrobe, Aphralysia anfracta, recently described from the Chesterian of North Alabama, has now been found in a second outcrop of the same age, some tens of miles away from the type locality. This organism lived in the openings within mounds and reefs, encrusted larger objects, and also bound other components together. The new locality is the subject of current research and contains a moderately diverse fauna. Notice the characteristic corkscrew or sinusoidal form of some of the tubules of A. anfracta.
