Family Rhipidomellidae Schuchert, 1913 Rhipidomellid gen. et sp. indet.

Fig. 3I .

Material.—Two fragmentary specimens from the earliest Famennian (set II) of the trench Z−17.

Remarks.—This is one of the first brachiopods to appear immediately above the Frasnian–Famennian boundary in trench Z−17. Poor preservation of the specimen does not permit a more definite identification.
