This very rare Upper Liassic ammonite has only been documented from Britain and was first described by Young & Bird in 1822. It is thought to have descended from Harpoceras falciferum. The ammonite itself has mainly been preserved in solid calcite and has an immaculate centre. Discovered in 1989, this classic rarity would make an important addition for any serious collector. To our knowledge, only a handful of decent Ovaticeras from this locality, have ever been discovered.
