Oppelia is a haploceratcean ammonite and type genus for the Oppeliidae that lived during the Middle Jurassic between 170 and 164 million years ago.[1] Shells of Oppelia are involute with a small to moderate size umbilicus, bluntly rounded to sharp venter, and deeply impressed dorsum. Sides are generally smooth but may be variously ribbed on the outer flanks. Similar and related genera include Oxycerites and Oecotraustes.
