Spiraloconulus

Spiraloconulus is a genus of middle Jurassic forams with a coarsely agglutinated, microgranular, calcareous wall.

The test is large, conical to cylindrical, coiled somewhat straight; the early coiled stage results in a flattened apex.

Distinctly coiled microspheric tests are as much as 2 mm wide and 1.6 mm high.

Spiraloconulus is known from the middle Jurassic of France, Italy, Sardinia, and Arabia.

Timidonella is another spirocyclind from the same time, but with a wider distribution.
