SUMMARY Re‐interpretation of Cyrtina septosa Band (Lower Carboniferous) data from Derbyshire (England) by trend analysis reveals previously unrecognised but meaningful sedimentational patterns. Trends in geographic variation of number of shells; their disarticulation, orientation, and size; and thickness of the Band are judged to be indicative of water depth and turbulence, conditions of accumulation, and source.
