There is just something intrinsic about ammonites that is aesthetically pleasing to humans. Could it be the ammonite's Fibonacci spiral, observed in galaxies, the arrangement of leaves around a stem, and the shape of ammonite shells? 65 million years extinct, this Ammonite is an awesome piece of nature, with its 11" spiraling surface and cradle-like matrix. It comes with an educational booklet to tell the story of this alluring ancient sea creature.
