globigerina
''Globigerina'' is a genus of planktonic Foraminifera that have populated the world's oceans since the Late Eocene.
==''Globigerina'' ooze==
Vast areas of the ocean floor are covered with ''Globigerina'' ooze, dominated by the foraminiferous shells of ''Globigerina'' and other Globigerinida. 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, which turned out to be mainly composed of the shells of ''Globigerina bulloides''.
