Globigerina

Globigerina () is a genus of planktonic Foraminifera, in the order of Rotaliida. It has populated the world's oceans since the Middle Jurassic.

==Globigerina ooze== Vast areas of the ocean floor are covered with Globigerina ooze, dominated by the foraminiferous shells of Globigerina and other Globigerinina. The name was originally applied to mud collected from the bottom of the Atlantic Ocean when planning the location of the first transatlantic telegraph cables and it was mainly composed of the shells of Globigerina bulloides.
