Sloppy science in the Bad Astronomy book. Right at the start of the quoted section, the BA says the shell is made of calcium. Later he correctly says calcium carbonate. The two are NOT synonomous. Calcium is a soft, light, highly reactive metal. Calcium carbonate is the stuff of egg shells, sea shells and limestone.

I think sloppy is too strong a word. We say you need calcium for your bones, but really we mean calcium carbonate. So it's not so much sloppy as it is a shortcut, almost an expression. I don't think using it in this context is incorrect.

After all, there is a good deal of calcium in calcium carbonate...
