Prompt used to create the image

Scientifically accurate paleoart of Torvosaurus, a carnivore Megalosauridae dinosaur from Callovian–Tithonian times (165.3–143.1 million years ago). Bipedal with the back held roughly horizontal and the tail held straight out behind for balance, never dragging on the ground. NOT standing upright like a kangaroo. Mouth closed with all teeth fully hidden behind scaly lips, like a monitor lizard. NO visible teeth. Hands held tucked in near the chest with the palms facing inward toward each other, like clapping, claws curving inward and forward. NOT hanging down, NOT palms-down, NOT claws pointing at the ground. A large predator about 10 meters long with a long, low skull and strong arms with three clawed fingers, skin of small scales. Reference: Torvosaurus is a genus of large megalosaurine theropod dinosaur that lived approximately 165 to 146.5 million years ago during the Callovian to Tithonian ages of the late Middle and Late Jurassic period in what is now Colorado, Portugal, Germany, and possibly England, Spain, Tanzania, and Uruguay. It contains two currently recognized species, Torvosaurus tanneri and Torvosaurus gurneyi, plus a third unnamed species from Germany. Anatomy: three main weight-bearing toes on each foot. Full body in side view, whole animal visible, standing in a Jurassic landscape with conifers, cycads, ginkgoes and ferns, no grass and no flowering plants. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
