Hyper-realistic cinematic documentary still, style of BBC Prehistoric Planet. Extreme close-up low angle shot. On the left, the massive, imposing head of a green-skinned T-Rex dominates the frame, its jaws slightly open to reveal sharp teeth and saliva, staring down with a predatory yellow eye. On the right, standing on the rough, leathery, hill-like skin of a dead sauropod carcass, a small, feathered Troodon looks up in terror, posture tense and ready to flee. The texture of the T-Rex's scales and the Troodon's feathers are incredibly detailed. Bright natural sunlight, harsh shadows, blurred coastal background with green cliffs and blue sky, 8k resolution, photorealistic, depth of field.
