Nostoceras is a genus of heteromorph ammonite known from Late Cretaceous sites all over the world (California, Mexico. British Columbia, Angola, Madagascar, Japan, and New Zealand but it appears on the market only occasionally.  It is an especially in-demand ammonite due to that rarity.

It’s hard enough to find just one specimen but here’s a great matrix piece with two of them on it.
