Create a 10-second ultra-realistic high-speed pursuit shot of a velociraptor sprinting across an endless grassland. The camera is physically locked just behind the dinosaur’s tail, as if mounted to its body, maintaining a tight trailing perspective. The muscular tail dominates the foreground, swaying with precise counterbalance as powerful leg strides drive the creature forward. Skin texture stretches and compresses over defined muscles, subtly vibrating from speed and airflow. The velociraptor accelerates into a full sprint. Motion is extremely fast yet biomechanically accurate: elastic spine flexion, explosive hind-leg extension, and razor-sharp foot impacts. Tall grass bends and ripples in waves as the raptor tears through it; dirt, seeds, and small debris scatter naturally. The ground trembles slightly from each step, conveying authentic mass and force. Camera behavior: aggressive forward velocity with strong motion parallax across the grassland and distant horizon, while the tail remains relatively stable due to the locked camera position. Micro-bounces synchronize perfectly with each stride cycle. Natural wind roars past, grass hisses, and the raptor emits deep, rhythmic breathing with occasional sharp screeches. Lighting is natural daylight with continuous shadows flickering beneath the running body. No slow motion, no cuts, no stylization. Pure prehistoric kinetic realism — raw speed, real physics, and predatory energy — ending mid-sprint as acceleration continues
