A scene on Earth during the Ordovician period

A highly realistic depiction of a coastal scene on Earth during the Ordovician period, featuring shallow marine waters teeming with diverse ancient sea life such as trilobites, brachiopods, nautiloids, and crinoids. The shoreline is rocky and barren, with no terrestrial plants, under a clear blue sky. Rich detail and natural lighting emphasize the textures of early marine organisms and the pristine, untouched environment of prehistoric Earth.
