Science / Geology / Foraminifer: A group of single-celled organisms, mostly marine, that produce a calcium carbonate shell. Their shells can make up a significant portion of the carbonate sediment in some areas.
Science / Biology / Foraminifera: Single-celled protists that secrete a shell or test. Accumulations of the shells of dead foraminifera and other microscopic sea creatures form chalk deposits. MORE
Science / Geology / Foraminiferal Ooze: A calcareous sediment composed of the shells of dead Foraminifera. MORE
Science / Geology / Pelagic Sediment: A ocean sediment that accumulates far enough from land that detrital materials are a minor component. These sediments are largely composed of the tiny shell debris of radiolarians and foraminifera. MORE
