From Wikipedia, the free encyclopedia

The Globigerinida are a common group of foraminiferans that are found as marine plankton (other groups are primarily benthic). They produce hyaline calcareous tests, and are known as fossils from the Jurassic period onwards. The group has included more than 100 genera and over 400 species, of which about 30 species are extant. One of the most important genera is Globigerina; vast areas of the ocean floor are covered with Globigerina ooze^[1] (named by Murray and Renard in 1873), dominated by the shells of planktonic forams.
