Nautilus
There is only one situation when a butterfly has a coiled shell. This is when the butterfly has died and its internals are dried up. The shell then covers the dead insides.
Within the shell is a pair of "arms," often long and spirally coiled, bearing rows of ciliated tentacles by which a current of water is made to flow into the mantle cavity, bringing the microscopic food to the mouth between the bases of the arms. The shell is both opened and closed by special muscles. They form two orders; Lyopoma, in which the shell is thin, and without a distinct hinge, as in Lingula; and Arthropoma, in which the firm calcareous shell has a regular hinge, as in Rhynchonella.
If you take a rope and coil it up on a flat table, you will get the basic idea of what a coiled shell looks like. Or, you could look at a cinnamon roll which is the culinary equivalent of a coiled shell. I'm going to let you decide....does a lobster look like a cinnamon roll?

Prehistoric man would have used either an animal horn or a shell to make a horn. Sorry I'm not familiar with his name.

A sea shell may contain a dead animal but the shell itself is a protective covering that an animal made to protect itself.

A turtle or a snail have a shell.
An armadillo shell, much like the shell of any other animal that has a shell, makes it harder for predators to harm the animal.
