The test, or shell, may be trochospiral to planispiral throughout, or just in the early part with the later part uncoiled. Chambers may be somewhat enveloping, and attached forms may uncoil in the adult. In coiled forms, the aperture is interiomarginal, or terminal in uncoiled forms. The test wall is of perforate hyaline (glassy) oblique calcite, appearing optically granular.

gollark: I'm not sure it fixes much though. You still have to keep giant timezone databases around, and extra transitional logic, on top of the new ones.
gollark: More so than utter UTC, yes.
gollark: Oh no.
gollark: A bunch of places will have to switch. Timezone databases will need updating, as will basically all signs and stuff. A UTC migration would have the same sign-updating things, but no timezone-database issues and much less ambiguity there.
gollark: It still has almost exactly the same problems plus fun new ones.
