The term "trifidum flora" was based on acritarchs from, possibly, the Tetragraptus approximatus Biozone of northwest England. It has been suggested as an index horizon for the base of the Arenig Series but may represent a number of assemblages of slightly different age, and the index species. Stelliferidium trifidum, first described from the Tremadoc Series of Shropshire, is not always present. The diagnostic potential of other acritarchs, especially Peteinosphaeridium sp., is noted and relevant material from south central and southeast Turkey reviewed.
