Individual collected in Saanich Inlet, Vancouver Island, British Columbia. This species was particularly common in brackish-water assemblages but was also found in marine conditions.

This small foram (about 100 microns across) is living on the surface of the test of a much larger foram, Bathysiphon filiformis. The Bathysiphon test is 600 times as long as the Tritaxis one.

A side view of the test, which is 1.1 mm long. The aperture is toward the top; the bottom forms the tight coil typical of species in this genus. Image courtesy of David B. Scott, Dalhousie University. This image was originally published in
Palaeologica Electronica, vol. 3, issue 2, and is used with the kind permission of that journal and the Paleontological Association.

Collected in an inlet of Oslofjord, Norway. Unlike its relative, Ammoscalaria pseudospiralis, A. runiana is found more commonly in mudflat areas than in typical marine conditions in the Oslofjord.

This empty test is beginning to show signs of decay. The study of the process of decay is called taphonomy; understanding the processes that cause certain changes in foraminiferal tests after death is very important for the reconstruction of paleoenvironments.

This test, which no longer contains a living foraminiferan, is beginning to decay. The small chambers at the top of the test are gone, leaving a spiral of holes where they once were.
