A SEM study on the test wall of Quasifusulina has demonstrated that the ultrastructures in the spirotheca Quasifusulina different from those of related fusulinid genera, such as Fusulinella and Triticites. The primary wall structure is prokerotheca rather than diaphanotheca or keriotheca, as previously described. The peculiar wall structures of Quasifusulina may represent a previously unknown type of spirotheca in fusulinid Foraminifera. □ Foraminifera, ultrastructure, spirotheca, biomineralization, Carboniferous, Permian.
