The genus name "Ammobaculites" means "sandy walking stick". As you can seem the early chambers (at bottom) coil like the top of a cane, but later chambers grow in a straight line. Individual isolated from the Hamble estuary, southern England. Image courtesy of Dr. Elisabeth Alve, University of Oslo. Citation: Alve, E. and Murray, J.W. Ecology and taphonomy of benthic foraminifera in a temperate mesotidal inlet. Journal of Foraminiferal Research 24:18-27.

Ammotium species are important in estuarine environments; they often dominate shallow, hyposaline sediments. This sample was collected in an inlet of the Oslofjord, Norway.

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.

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.

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.

This species prefers deeper, stiller, more marine waters than other members of its genus. Image courtesy of Elisabeth Alve, University of Oslo. Originally published in J. Foram. Res. 16: 261-284; used with permission.
