Anabarella is a species of bilaterally-flattened monoplacophoran mollusc,[2] with a morphological similarity to the rostroconchs.

[3] Its shell preserves evidence of three mineralogical textures on its outer surface: it is polygonal near the crest of the shell, subsequently changing to both spiny and stepwise.

[4] Its name reflects its provenance from Anabar, Siberia.

[3] It has been interpreted as ancestral to the rostroconchs,[5] and has been aligned to the Helcionellidae.

[2] The genus is closely related to Watsonella, with which it bears many morphological similarities,[3] including a laminar internal shell microstructure said to connect it with the early bivalves Fordilla and Pojetaia.
