Prompt used to create the image

Scientifically accurate paleoart of Maip, a carnivore Megaraptoridae dinosaur from the Maastrichtian age of the Late Cretaceous (about 70 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. Long, strong arms with an enormous curved claw on the thumb and a large claw on the first finger. Reference: Maip is a genus of large megaraptorid theropod dinosaur from the Late Cretaceous (Maastrichtian) Chorrillo Formation of Santa Cruz, Argentina. The genus contains a single species, M. macrothorax, known from an incomplete, disarticulated skeleton. Maip may represent the largest megaraptorid known from South America, and possibly the world. Anatomy: three main weight-bearing toes on each foot; a large predator about 9–10 meters long with a long, narrow skull and long legs. Full body in side view, whole animal visible, standing in a cool Late Cretaceous floodplain in southern Patagonia, Argentina, like the Chorrillo Formation, with conifers, ferns and early flowering plants, no grass. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
