MICROFORAMINIFERA:

Hastigerina

return to definitionsMICROFORAMINIFERA: - Calcareous, unicellular marine organisms,with alternating or spirally-arranged, progressively larger cells (bottom right). The chitinous inner linings of benthic foraminifera are common in pollen preparations of marine or esturine sediment. These chitinous remains vary in their size, the shape and arrangement of the cells, and in their ornamentation. Spiral forms (coiling either direction) are most common, but zig-zag, linear, and other forms also occur (Stancliff, 1989).
