MCKINNEY, F. K., BURDICK, D. W. 2001. A rare, larval-founded colony of the bryozoan Archimedes from the Carboniferous of Alabama. Palaeontology, 44, 5, 855–859.
Frank K. McKinney and Dennis W. Burdick Very few basal attachments of the spiralled fenestrate bryozoan Archimedes are known. A newly discovered specimen is interpreted to have grown on a thin cylindrical ephemeral substratum that extended above the sediment-water interface, allowing paired spirals to develop and to extend in opposite directions when the colony was very small.
