怒吼的棘龍大步穿越叢林河流

A highly realistic Spinosaurus walking powerfully across the surface of a river, its long crocodile-like snout open in a roar, sharp teeth visible, and water splashing around its legs. The dinosaur has a tall distinctive sail on its back, textured scaly skin, and a muscular but natural quadrupedal/bipedal body structure true to paleontological reconstructions. The background features a dramatic cloudy sky, dense jungle, and misty atmosphere. Photorealistic, ultra-detailed dinosaur anatomy, cinematic lighting, dynamic water effects, 8k resolution --stylize 400 --v 6
