MURRAY, J. W. 1973. Wall structure of some agglutinated Foraminiferida. Palaeontology, 16, 4, 777–786.
J. W. Murray Present knowledge of agglutinated wall structure and composition is briefly reviewed. Examination of 19 recent species shows the existence of three wall types: simple imperforate wall with an organic cement; complex alveolar imperforate wall with an organic cement; 'perforate' wall with a calcareous cement. It is concluded that more attention should be paid to wall structure and composition in descriptions of species and in taxonomy. Forms with a calcareous cement seem to be stenohaline marine or hypersaline and therefore useful indicators of environment. The Palaeontological Association (Free Access)
