Anabarella is a species of bilaterally-flattened monoplacophoran mollusc,[1] with a morphological similarity to the rostroconchs.[2] 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.[2] Its internal microstructure is calcitic and semi-nacreous.[3] Its name reflects its provenance from Anabar, Siberia.[2] It has been interpreted as ancestral to the rostroconchs,[4] and has been aligned to the Helcionellidae.[1]

The genus is closely related to Watsonella, with which it bears many morphological similarities,[2] including a laminar internal shell microstructure said to connect it with the early bivalves Fordilla and Pojetaia.[5]
