Use in stratigraphy
[edit]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.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
