Abstract

Necdetina (type species N. taurica n. sp.) is described here as a new fusulinoidean genus with a replaced or recrystallized wall from the Middle Permian (Capitanian) of Turkey. In addition to its distinctive wall structure, which was probably originally keriothecal and composed of aragonite or high-Mg calcite, the genus is characterized by an ovate shell with rounded to acute poles and axially elongated, biserially enrolled chambers. Chomata are absent, but inconsistently developed parachomata-like structures are present in the test where biserially enrolled chambers overlap. Circular foramina alternate in two rows at the bases of the apertural face and septa.
