Ancient Prehistoric Swamp Landscape

Create a highly detailed cinematic paleoart landscape showing a wet, alien-looking prehistoric swamp from the early land-plant era, with no animals or humans. The view is from low ground level across a shallow flooded marsh full of mossy green hummocks, slick mud, puddles, and winding rivulets reflecting a cold gray sky. Populate the foreground and midground with primitive vegetation: tall thin reed-like stalks with dark club-shaped tips, sparse brushy thickets, curled fern-like fronds, spiky low plants, bead-like wet growths, and exactly one prominent cluster of translucent pale green oval jelly-like sacs or seed pods in the lower right foreground, glowing subtly with brown vein-like interiors. In the distance, show flat-topped rocky mesas and low hills dusted with patches of snow, softened by drifting mist and steam rising in multiple wisps across the marsh. The atmosphere should be bleak, cold, ancient, and stormy, with heavy layered clouds, blue-gray lighting, damp surfaces, high realism, rich texture, scientific-documentary detail, wide-angle composition, deep depth of field, no text, no buildings, no modern objects.
