Description

The shell has rounded whorls and a deep rounded sinus on the upper lip of the aperture in place of the typical exhalent angulation of most related genera. Otherwise the shell is not obviously ornamented.

Species

According to the Paleobiology Database, the following species are included in this genus:

  • Sinutropis esthetica Perner, 1903[2]
  • Sinutropis interrumpens Perner, 1903[2]
  • Sinutropis spiralis Rohr, 1988[2]
  • Sinutropis tenera Perner, 1903[2]
gollark: It seems harder to shield humans and the weird biological processes which get affected against radiation than computers, where it basically just boils down to more redundancy and possibly better materials/processes.
gollark: (there's ECC support in RAM and SSDs and stuff, but as far as I know they just put radiation shielding on for CPUs)
gollark: Stuff is generally not designed for an environment where bits might be flipped randomly at some point, though.
gollark: It's more "error rates increase" than "you slowly die", at least.
gollark: The logic gates operate at stupidly small scales, and are pretty sensitive.
