Extract

Toriyama and Kanmera (1968), in one of their studies of fusulines from the Rat Buri Limestone, Thailand, proposed two Permian fusuline foraminifer genera, Thailandina and Neothailandina. Based on these two genera they established the subfamily Thailandininae and placed it in the family Neoschwagerinidae. the tests of these genera are invariably replaced by secondary mineralization to a finegrained mosaic calcite such as seen in specimens of Staffellidae. the thailandinid wall was apparently originally composed of a tectum and keriotheca.
