| 背面描述 | A full-colour depiction of a Dunkleosteus, the armoured predatory fish of the Late Devonian period, occupies the central field against a deep-blue underwater background with scattered air bubbles rendered in colour. The creature is shown in left-facing profile with its distinctive bony-plated head and open jaws prominently displayed. The species name DUNKLEOSTEUS and its geological range 380-360 MIO YEARS BC are inscribed in the upper field, with the issue year 2023 below. Geological period inscriptions arc around the inner border: DEVONIAN 416-360 MIO. YEARS BC on the left, CARBONIFEROUS 360-298 MIO. YEARS BC along the bottom, and PERMIAN 298-250 MIO. YEARS BC on the right. The legend PREHISTORIC LIFE arcs prominently along the upper rim. |
