Tony salterella tarantella
Salterella is an enigmatic Cambrian–Ordovician genus with a calcareous shell that appears to be septate, but is rather filled with stratified laminar deposits. Its shell contains grains of sediment, which are obtained selectively (with a preference for denser grains) by a manner also observed in foramanifera.
