Fossils in general provide geologic clues to the environment of deposition, rock formation, and the types of biological activities present at the time. Index fossils are more helpful in providing geologic references or reference markers. When polished as tiles or slabs, fossil bearing rocks are used as attractive building facades and pavements.

These corals are found as fossils in almost every fossil site in Michigan. This is because the Devonian was a time of great reefs, which covered most of the world's oceans.
