Tropitidae have subspherical to discoidal, involute to evolute shells with long body chambers and a ventral keel bordered by furrows. The surface may have ribs, nodes, or spines, or may be smooth. The suture is generally ammonitic, but may be ceratitic to goniatitic.
The derivation of the Tropitidae is uncertain but they seem to form a group along with the Tropiceltitidae and Haloritidae within the superfamily.

gollark: I think they should probably just be capped at 8 years or so, or a bit longer if the author provides the source, to be released when it's up.
gollark: Also, proprietary programs *may* use incompatible library versions and stuff sometimes, but you can probably get around that.
gollark: You may also need to turn off Secure Boot though, and x86 tablets often have UEFI weirdness.
gollark: I'm not sure if distro installers detect this, but it's not too hard to install the right bootloader manually.
gollark: This may be harder on those old x86 tablets because they have a weird setup with 32-bit UEFI and 64-bit processors for some odd reason.
