Oymurania is an organophosphatic Cambrian small shelly fossil interpreted as a stem-group Brachiopod. It consists of a pair of Micrina-like shells that broadly follow a logarithmic coiling trajectory with a high rate of expansion.[1]

Microstructure

Its shell comprises an inner prismatic layer, with hexagonal prisms that run through the full depth of the layer, and an outer layer that contains an acrotretid-like microstructure of surface-parallel laminae punctuated by pore-bearing rod-like columns.[2]
