Belongs within: Foraminifera.Contains: Stannophyllum, Psamminidae. The Xenophyophorea are a group of often large, deep-water protists (now believed to be a subgroup of the Foraminifera) that construct sessile tests of agglutinated particles. These particles are typically a mixture of foreign matter (xenophyae) and faecal masses (stercomare). Characters (Tendal 1972): Plasmodium (granellare) multinucleate, enclosed by branched tube… Continue reading Xenophyophorea

Psamminidae

Belongs within: Xenophyophorea. The Psamminidae are xenophyophores in which xenophyae are cemented together in plates or form a distinct surface layer (Tendal 1972). Characters (Tendal 1972): Test usually solid, may be fragile. External xenophyae arranged in a surface layer, sometimes several layers present. Very little cement used. <==Psamminidae |–SemipsamminaMS98 |–Cerelpemma Laubenfels 1936T72 | `–*C. radiolarium (Haeckel 1889) [=Psammopemma radiolarium]T72 |–Occultammina Tendal, Swinbanks… Continue reading Psamminidae
