Description: The white agglutinating foraminifera is Pyrgo sp. and the brown agglutinating foraminifera is Cribrostomoides subglobosum. The latter made made up about 98% of the sieved macrofauna samples (sieved on a 0.50 mm sieve) at Dalsnuten. Item Type: Image Title: Pyrgo sp. Copyright: SERPENT project Species: Pyrgo sp.

This foram is extremely common in the Ross Sea (Antarctica). The "porcelaneous" structure typical of miliolid tests (rotalids have glassy "hyaline" tests) is very conspicuous here. Image courtesy of Samuel S. Bowser, Wadsworth Center.

Extreme macro: take a good binocular microscope, a good camera and just focus your microfossils ;)

Triloculina (try-lock-you-lean-a) is an intertidal benthic foraminifer, with a small number of elongate chambers. Test usually said to be calcareous (porcellanous) but is brown coloured. With several major chambers. Pseudopodia mostly arise from the aperture (left). Phase contrast.
