Introduction. Foraminifera are amoeboid protists (Kingdom Protista) that produce protective shells, also known as tests, which have openings or foramina for the extrusion of pseudopodia, from which the group derives its name. they are considered to comprise a taxonomic order, the Foraminiferida, within the rhizopod subclass Granuloreticulosa.

These characteristics make them important tools for reconstructing ancient oceans. or electron microscopy.

Foraminifera may be planktonic or benthic, are mainly marine, and are found in all marine environments. Mostly less than one millimeters in size, they range from

Distribution: Late Miocene to recent, cosmopolitan, where water temperature reaches 17°C at least one month, in the Atlantic reaching from 62°N till 55°S, in the Pacific from 48°N till 33°S. 2015-10-28 · A microscopic image of a live planktonic foraminifera. The “hairs” radiating from the centre are called pseudopodia and are 1 to 1.5 millimeters long.

Foraminifers produce networks of reticulopodia (Figure 1), which are characteristic of the Phylum Granuloreticulosa . The functions of the reticulopodia include

The functions of the reticulopodia include The generally accepted classification of benthic foraminifera is based on characteristic test morphol- ogies (morphotypes). While more recent molecular studies Foraminifera (formally called Foraminiferida) are amoeba-like, single-celled protists (very simple micro-organisms).

2020-10-01 · A typical characteristic of the foraminiferal fossils analysed in this study is the presence of the ‘Unilocular’ interruptive zone, which directly overlays the Eoendothyra communis-Quasiendothyra kobeitusana zone, indicating the Devonian-Carboniferous boundary.

While the phylum has also been shown to consist of several slime moulds and Foraminifera, it's mostly composed of naked and testate amoebae. Unlike naked amoebae, testate species are covered by a shell-like structure which may consist of small grains of sand, diatoms, mineral particles, and silica plates.
