Tannuolina is a genus of tommotiid, belonging to the brachiopod stem lineage.
Its phosphatic shells exhibit a complex series of open pores/chambers/channels in outer shell layer. [1] [2] It is conventionally interpreted as an essentially bivalved organism, similar to Micrina, though some use the unequal ratio of stellate to mitrate sclerites to argue for a halkieriid-like anatomy. [3]
More recently a tube-like construction inspired by Eccentrotheca has been proposed. [4]
