Agglutinated Foraminifera build their test of particles cemented together. Some species use whatever particles are available, while other species may select only sponge spicules, diatoms, mica flakes or certain sized particles to build their test.
Rhabdammina abyssorum M. Sars, 1869 from the South China Sea (3465m depth) using diatoms and other particles to build its test. see the whole specimen
Saccorhiza ramosa (Brady, 1879) from the South China Sea (3465m depth) likes sponge spicules to build its test. see the whole specimen
Here we show recent foraminifera. The material used by fossil agglutinated foraminifera may be used for special investigations of past geological events. Such an example are shock-diamonds found in tests after the Cretaceous/Paleogene boundary. The size of the diamonds found worldwide increase with proximity to the impact crater in Yucatan, Mexico.
