Streptocyclammina is a genus of benthic forams with a flattened test from the Jurassic.
The test (or shell) usually starts off streptospiral (coiled irregularly) hence the name, and becomes planispiral in the mature stage.
The wall is finely agglutinated, externally imperorate, internally with massive septa perforated by numerous apertures.
Streptocyclammina has been found in Jurassic sediments in Morocco, Italy, and the Balkans.
Spiraloconulus and Timidonella are other spirocyclinids from the same general region, but are limited to the middle Jurassic.
