Expand your collection with a genuine Atlantic rarity from the Cypraeidae family. The Trona stercoraria (also known as the Rat Cowrie) is the only extant species of its genus and captivates with its heavy, rounded form. Its unique, distinctive color pattern consists of a fine olive-brown to dark speckled dorsal surface, contrasted by dramatically dark, almost black flanks and a deep dark brown base. With an excellent collector’s size of 71 mm, this piece presents a perfectly preserved, mirror-smooth enamel layer with an intense deep gloss. Origin This authentic collectible comes from the Atlantic waters off Belente, Senegal (West Africa). The recovery is usually carried out by local fishermen or divers in rocky zones and in strict compliance with marine conservation guidelines.
