Definition

  • according to Hottinger (2006):

AGGLUTINATED - shell texture characterized by components gathered in the ambient environment and bound by organic or biomineralized cements produced by the cell. Particles may be selected according to size and shape to form a closefitting mosaic. Often, the agglutination in the external and internal parts of the wall is differentiated but there are no sharp boundaries. See also: wall polarity).
