The empty tests of dead foraminifera behave as sedimentary particles and are subject to transport, although their different shapes and effectively low density means that their hydraulic equivalence is greater than that of spherical quartz grains (see Haake, 1962). Their estimated traction velocities range from c. 4 cm s-1 to c. 13 cm s-1 (Snyder et al., 1999). The presence of calcareous foraminiferal tests in a fossil sedimentary deposit would normally be taken as an indication of deposition in a marine environment. However, it has long been known that wind can transport...
