Use in stratigraphy

Ozarkodina snajdri forms a subdivision of the Pseudomonoclimacis latilobus graptolite zone in the Burgsvik beds Silurian formation in Sweden.^[2] An Ozarkodina snajdri crispa zone has also been identified in the Wills Creek in Virginia.^[3]

Ozarkodina derenjalensis is found in the Silurian of the Niur Formation in Iran.^[4]

The Kellwasser event in the Devonian which saw the extinction of all Ozarkodina species is reported in the list of Global Boundary Stratotype Sections and Points.
