Prompt used to create the image

Scientifically accurate paleoart of Tarbosaurus, a carnivore Tyrannosauridae 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. Reference: Tarbosaurus is a genus of large tyrannosaurid dinosaur that lived in Asia during the Maastrichtian age of the Late Cretaceous period. It contains the type and single species Tarbosaurus bataar, which is known from the Nemegt Formation of Mongolia, with more fragmentary remains found further afield in the Subashi Formation of China. Tarbosaurus is represented by dozens of fossil specimens, including several complete skulls and skeletons. Anatomy: three main weight-bearing toes on each foot; skin predominantly covered in small scales; massive deep skull, short two-fingered arms, powerful hind legs. Full body in side view, whole animal visible, standing in a humid Late Cretaceous river floodplain forest like the Nemegt Formation of Mongolia, with conifers and broadleaf flowering trees, no grass. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
