Rotaliida
Encyclopedia : R : RO : ROT : Rotaliida
The Rotaliida are a large and abundant group of foraminiferans. They are primarily oceanic benthos, although some are common in shallower waters such as estuaries. They also include many important fossils, such as nummulites. Rotaliids produce hyaline tests, in which the microscopic crystals may be oriented either radially (as in other forams) or obliquely.
