| 背面描述 | The reverse depicts a detailed high-relief rendering of Titanoboa, the massive prehistoric snake, shown coiled and in motion across a primordial landscape with rocky terrain in the background. The species name TITANOBOA and its temporal range 60-58 MIO YEARS BC appear in the upper central field, with the year of issue 2023 below. The arc legend PREHISTORIC LIFE runs along the upper border. Three geological period references are inscribed along the periphery: CRETACEOUS 145-66 MIO. YEARS BC on the left, TERTIARY 66-2.6 MIO. YEARS BC along the lower border, and QUATERNARY 2.6 MIO. YEARS BC-TODAY on the right, providing a geological timeline context for the depicted creature. The design is executed in finely detailed relief with a contrasting dark background. |
