Lingulosacculinae

Balthasar, Uwe & Butterfield, Nicholas J., 2009, Early Cambrian “ soft-shelled ” brachiopods as possible stem-group phoronids, Acta Palaeontologica Polonica 54 (2), pp. 307-314 : 308

Subfamily Lingulosacculinae nov.

Diagnosis.— Lingulellotretidae with non−mineralised shells; all other characters as for family.

Included genera.— Lingulosacculus gen. nov.

Remarks.—The published images (Zhang et al. 2007: fig. 4; Zhang et al. 2008: fig. 4J) of the soft−shelled lingulid that is referred to as “ Wangyuia chengjiangensis ” in Zhang et al. (2007) are sufficient to justify its inclusion in the Lingulosacculinae , including lack of mineralisation. However, this brachiopod has not yet been legitimately published.
