Create an ultra-realistic cinematic fantasy scene in a lush prehistoric jungle valley, vertical 9:16. A colossal Spinosaurus stands beside a shallow river with its long crocodile-like jaws stretched wide open. A young adult woman sits calmly inside the open mouth, perfectly centered, with her legs hanging slightly forward. She has straight dark hair, a composed fearless expression, and realistic skin texture. She wears a fitted black long-sleeve crop top, blue denim shorts, and black knee-high combat boots. Small blood smears and light scratches appear on her clothing and legs, adding dramatic tension without gore. She gently cradles a small baby dinosaur in her arms, holding it protectively. Behind them, a tall dramatic waterfall cascades down steep jungle cliffs covered in dense green foliage and mist. Several dinosaurs populate the scene: Velociraptors stalk the riverbank, small herbivores run through the background, and pterosaurs circle overhead. Build a rich environment with mossy rocks, flowing water, tropical plants, and soft atmospheric fog. Use cinematic natural lighting with diffused daylight, detailed shadows, sharp focus on the woman and Spinosaurus, and shallow depth of field for background elements. Render hyper-real textures on dinosaur scales, teeth, water droplets, foliage, and fabric. Epic fantasy realism, dramatic composition, ultra-detailed photorealism, 4K quality, cinematic color grading, no text, no watermark.
