| 背面描述 | The reverse presents a detailed skeletal fossil depiction of Edaphosaurus, the Carboniferous-period synapsid, shown in partial anatomical view occupying the majority of the field. The characteristic tall neural spine sail is prominently rendered in high relief extending across the upper portion of the design, with vertebrae, ribs, and limb bones rendered with scientific precision. The skull of the creature is depicted to the right in three-quarter view, showing dentition and cranial structure. Along the upper right rim, the species name 'Edaphosaurus' is inscribed in an arc in Latin lettering. At the lower centre, the date '2022' appears flanked by a small decorative ammonite motif, with the series name 'EVOLUTION' inscribed in bold letters along the lower field. |
