A genus of small marine foraminifera (single-celled organisms with shells), characterized by having two distinct chambers in their shell structure.
Scientific Latin noun from 'bi-' (two) and 'loculus' (chamber), with the feminine Latin ending '-ina,' creating a taxonomic genus name following Linnaean nomenclature.
Biloculina are fossils that have been accumulating in ocean sediments for millions of years—their tiny two-chambered shells are so numerous that they contribute significantly to ocean floor deposits and help geologists date rock layers!
