Description
Test free, early portion close coiled, later uncoiled and rectilinear, rounded in section; wall agglutinated, interior simple; aperture terminal, rounded. [Ammobaculites differs from Haplophragmium in its early planispiral, rather than streptospiral coil, from Ammomarginulina in its straight sutures and centrally placed aperture, and from Ammoscalaria in its thicker septa, which represent apertural faces of previous chambers, rather than being pseudochitinous and of secondary origin.]
