三畳紀のイクチオサウルス vs バイオニックムカデの戦士

A cinematic 16:9 underwater suspense scene. In the sun-drenched, emerald-green ocean of the Triassic period, a chilling eight-meter-long, matte-black bionic centipede armor, with 20 pairs of gleaming metallic paddle-like legs, moves with incredible agility and imposing presence, a sci-fi warrior. Just meters away, a 15-meter-long giant ichthyosaur (Cymbospondylus) confronts it, with an eel-like tail and a long, narrow snout, surrounded by churning bubbles and scattered sand. Sunlight filters through the clear water, revealing incredibly detailed mechanical textures, realistic cinematic volumetric lighting effects, and 8K resolution. --ar 16:9
