Diagnosis. An irregular and asymmetrical cluster of variable outline constituted by circular to subcircular pits in calcareous shells of brachiopods. The pits at the centre of the group are smaller than peripherals. Internal moulds of the small pits are short and rounded, while the large are typically conical or subcylindrical, having the external mean diameter/length ratio close to 1.
