A medium shot, side-profile anime illustration of a Ceratosaurus, a prehistoric theropod dinosaur, positioned centrally in a prehistoric wilderness. The creature is depicted with scaled, earthy-brown skin and a distinctive small horn on its snout, with smaller horns above its eyes and a row of bony osteoderms running down its back. It is captured in a mid-stride pose, with its powerful legs tensing and its three-toed claws gripping the fertile earth, while its long tail balances its weight. The background features a lush, primeval jungle with towering ferns, giant mossy conifers, and a dense canopy of tropical greenery under a hazy, humid sky. The atmosphere is wild and ancient, lit by dappled sunlight filtering through the leaves, creating high-contrast shadows and a vibrant green and amber color palette with a slight atmospheric haze and depth of field blurring the distant foliage.
