Spiraloconulus ✝
| Description | Spiraloconulus is a genus of middle Jurassic forams with a coarsly agglutinated, microgranular, calcareous wall. The test is large, conical to cylindrical, coiled to straight(ish); 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. Megalospheric tests are smaller, up to 1.5 mm high and 1.1 mm wide.
