Pseudotriquetrorhabdulus inversus (Bukry & Bramlette, 1969) Wise in Wise & Constans, 1976

Description: Large, narrow, spine-like nannofossil that tapers towards both ends and has a narrow central canal.

Remarks: Originally compared with Neogene Triquetrorhabdulus due to presence of ‘keels' but may represent disarticulated rhabdolith spines.
