| 背面描述 | A highly detailed, ultra-high-relief depiction of an ammonoid fossil (Ammonoidea) dominates the field, rendered in rose gold-toned silver against a textured, antique-finished rocky matrix background that evokes a natural stone surface. The coiled cephalopod shell displays finely struck ribbing and suture lines with exceptional three-dimensional depth. Two smaller ammonite fossil motifs appear in low relief in the lower left field, providing a sense of scale and compositional balance. The inscriptions AMMONOIDEA, DEVONIAN PERIOD, and EVOLUTION of Life are distributed around the design, with the date 2018 appearing in the lower field. |
