例文

- The septa become confined to the dorsal side of the shell resulting in a series of dorsal chambers, or camerae, that provided stabilizing buoyancy.
- Cameral deposits are well developed and are thick, almost filling the ventral portion of the more apical chambers but also found in dorsal chambers as well.
