Prompt
"Generate an image of a serene Ordovician ocean scene, 450 million years ago, teeming with diverse marine life. Include trilobites, brachiopods, graptolites, nautiloids, conodonts, and crinoids in the water, with a coral reef in the background. The sea floor is covered with fossils, and in the distance, the supercontinents of Gondwana, Laurentia, Baltica, and Siberia are visible as shorelines. The climate is transitioning from warm to cool, with a hint of ice caps forming. The scene should reflect the Great Ordovician Biodiversification Event, showcasing the explosion of marine life during this period. The style should be scientifically accurate and evocative of a bygone era, similar to a National Geographic illustration."
