Large Turritella mauretanica Fossil on Matrix – Eocene Marine Gastropod A rare and visually striking fossil of Turritella mauretanica, preserved within its original sedimentary matrix. This marine gastropod lived during the Eocene epoch (56–33.9 million years ago), when warm seas supported abundant and diverse marine ecosystems. The shell measures over 7.5 cm in length with an approximate diameter of 3.5 cm, making it a notably large example for the species. Its elegant, elongated spiral is clearly defined, offering a beautiful representation of the natural geometry typical of these ancient sea snails. The specimen has been carefully cleaned and prepared to enhance visibility while maintaining its natural character. The contrast between the fossilized shell and the surrounding rock adds depth and presence, making the piece equally suitable for scientific appreciation or refined display. An excellent choice for collectors, natural history enthusiasts, or anyone seeking an authentic fossil that captures the quiet beauty of prehistoric marine life.
