Rhynchonellata - Rhynchonellida - Tetrarhynchiidae

Taxonomy
Rhynchonella subconcinna was named by Davidson (1852). It is a 3D body fossil. Its type locality is Ilminster (Marlstone Rock-bed, BMNH), which is in a Spinatum carbonate limestone in the Marlstone Rock-bed Formation of the United Kingdom.

It was recombined as Tetrarhynchia subconcinna by Ager (1956) and Gahr (2002).

Synonyms
  • Rhynchonella fodinalis was named by Tate (1876). It is a 3D body fossil. Its type locality is Eston Mine (GSM collection), which is in a Spinatum marine horizon in the Cleveland Ironstone Formation of the United Kingdom.

    It was synonymized subjectively with Tetrarhynchia subconcinna by Ager (1956).
