Dentaliida

Dentaliida is one of the two orders of scaphopod mollusks, commonly known as elephant's tusk shells. The order Dentaliida contains most of the larger scaphopods, and is distinguished from the other order (the Gadilidae) by the shape of its shell (the Dentaliid shell tapers uniformly from anterior to posterior; the Gadilid one has an anterior shell opening slightly smaller than the shell's widest point), the shape of the foot (the Dentaliid foot is boat-shaped with a central trough; the Gadilid foor is star-shaped), and the arrangement of some of their internal organs.

gollark: I probably know more maths things™ than people from around then generally did, but not much of the history or motivation or how they did things without modern calculators and such.
gollark: Anyway, see, cyber, your knowledge of modern-day things are probably *not* amazing cutting-edge knowledge until maybe 1600, but then you can't do much because they lack the technology to do much.
gollark: If you want "much better computers" it will be harder, of course.
