| 正面描述 | The obverse features a large woolly mammoth rendered in profile, dominating the central field with naturalistic detail. In the foreground, a mammoth skull with elongated curved tusks is depicted, underscoring the paleontological theme of the series. A schematic timeline of the Quaternary period is incorporated into the design, providing geological context. The peripheral legend reads '2015 REPUBLIK ÖSTERREICH 20 EURO' along with the inscription '2,6 MIO QUARTÄR', referencing the 2.6 million-year span of the Quaternary. The overall composition reflects a high-relief artistic style consistent with Austrian Mint commemorative coinage. |

Part of Austria's long-running "Prehistoric Life" series, this 2015 issue focuses on the Quaternary period — the geological epoch beginning roughly 2.6 million years ago and, technically, still ongoing. Austria committed to the full series across multiple years, with each release coordinated with the Natural History Museum Vienna, whose paleontological collections directly informed the designs.
The .900 silver specification matches the fineness Austria maintained consistently across the series, a deliberate choice to align with earlier collector coinage traditions rather than the .925 standard more common among contemporary European commemoratives.
