An ammonite is a sea animal that lived a very long time ago and then died out. It had a spiral shell, often like a ram’s horn, and we know it from fossils — the shell turned to stone in rock. Children, collectors, and museums love them. The name comes from Ammon, an Egyptian god whose symbol was a ram’s horn; old writers called the fossil “the horn of Ammon.” Though actually, the same spelling is also used for a kind of explosive made from ammonium nitrate, but that is a factory and mining word. When people say ammonite in a classroom or a fossil shop, they mean the spiral sea creature in stone.
