sea urchin teeth

Here's some sea urchin teeth for my collection.

The chewing organ of sea urchins, which is composed of five teeth and a fleshy tongue-like structure, is called Aristotle’s lantern because it was described by Aristotle in his "History of Animals" as being similar in appearance to a horn lantern. (see in the comments)
