Membranous structures reflecting functional organs are recognizable in a relatively few tubular Bryozoa of Paleozoic age belonging largely to the order Trepostomata. Some skeletal structures also seem to reflect functional ...
Morphology, Anatomy, and Systematics of the Cinctiporidae, New Family (Bryozoa: Stenolaemata)

Boardman, Richard S.; McKinney, Frank K.; Taylor, Paul D. (1992)

The study of thin sections, peels, and SEM micrographs of skeletons, and sections of skeletons and soft parts together, has revealed new morphology and anatomy resulting in new growth and functional interpretations in a ...
Reflections on the Morphology, Anatomy, Evolution, and Classification of the Class Stenolaemata (Bryozoa)

Boardman, Richard S. (1998)

Thin sections of 37 stenolamate species with soft parts within the skeletons unexpectedly reveal 10 variations in polypide anatomy and related methods of tentacle protrusion. Six of the variations modify attachment organs, ...
