Exempel på hur man kan använda FORAMS i en mening

• The base of the Piacenzian is at the base of the Gauss chronozone and at the extinction of the planktonic forams Globorotalia margaritae and Pulleniatina primalis.
• In 1913, naturalist Randolph Kirkpatrick published a book, The Nummulosphere: an account of the Organic Origin of so-called Igneous Rocks and Abyssal Red Clays, proposing the unconventional theory that all rocks had been produced through the accumulation of forams such as Nummulites.
• Near the top of the member several layers of tens of metres thick nodular and marly bioclastic limestones are present, containing marine benthic forams, the nodularity is derived from intense Thalassinoides burrowing.
• In 1966, Mayac dated the Callovian and what appeared to be the Lower Oxfordian stages with forams (Mayac, 1966, in Hirsch and Roded, 1996).
• It has been noted to consume filamentous cyanobacteria, diatoms, brown and red algaes such as seaweeds, seagrass, forams, hydrozoans, bryozoans, nematodes, bivalves, gastropods, crustaceans, and tunicates.
• The microfauna is not very diversified either, present are ostracods (in the marls), textulariids and pelagic forams (Hedbergella delrioensis, Heterohelix, and Globotruncana).
• Fissurina is a genus of unilocular (single chambered) calcareous forams, similar in general form to Lagena, but included in the nodosariacean family Ellipsolagenidae, Lagenida.
• Cornuspiracea comprise a superfamily of miliolid forams (Loeblich & Tappan, 1988) in which the test may be free or attached, planispiral or trochospiral, evolute or involute, spreading or discoidal.
• Saudia is a genus of large discoidal to reniform (kidney shaped) forams, with a relatively thick test and complex interior, composed of agglutinated matter, or microgranular calcite.
• Spiraloconulus is a genus of middle Jurassic forams with a coarsely agglutinated, microgranular, calcareous wall.
• Heterohelicoidea is a superfamily of middle Jurassic to Oligocene planktonic forams characterized by biserial or triserial tests, at least in the early stage, that may be reduced in the later stage but more commonly show chamber proliferation in the later stage.
• A few other amoeboids produce reticulose pseudopodia, and were formerly classified with the forams as the Granuloreticulosa, but this is no longer considered a natural group, and most are now placed among the Cercozoa.
• Because of their widespread distribution and abundance in sediments, forams have been the most extensively explored for their biological characters linked to paleoclimatic and paleoecologic reconstructions.
