Scientifically accurate paleoart of Velociraptor, a carnivore Dromaeosauridae dinosaur from Coniacian–Maastrichtian times (89.8–66 million years ago). Pose: walking with the whole body held horizontal and balanced over the hips like a seesaw, back parallel to the ground, head held low and forward at the same height as the hips, short neck curving forward rather than upward, long stiff tail extended straight back in line with the back. NOT standing upright, NOT a raised head, NOT an ostrich or kangaroo posture. Reference: Velociraptor is a genus of small dromaeosaurid dinosaurs that lived in Asia during the Late Cretaceous epoch, about 75 million to 71 million years ago (Mya). Two species are currently recognized, although others have been assigned in the past. The type species is V. mongoliensis, named and described in 1924. Fossils of this species have been discovered in the Djadochta Formation, Mongolia. Anatomy: bipedal with the back held roughly horizontal and the tail held straight out behind for balance, never dragging on the ground; hands with palms facing each other (not pronated), three-toed feet; lips covering the teeth when the mouth is closed; a long, low, narrow snout with a slightly upturned profile and rows of small serrated teeth, NOT a bird beak and NOT a rounded bird head; a short S-curved neck about as long as the skull, NOT a long ostrich neck; clearly visible arms folded at the sides of the body like a bird's wings, with long pennaceous feathers attached along the forearm and hand, and three separate clawed fingers visible at the end of each hand; a stiff, straight tail held horizontally, fringed with feathers along its sides; each foot has a small sickle-shaped claw on the second toe, retracted and held just off the ground, proportionate in size and attached to the toe; the animal walks on the third and fourth toes; body covered in short feathers, about 2 meters long including the tail and about 50 cm tall at the hip. Full body in side view, whole animal visible, standing in an arid Late Cretaceous landscape of red sand dunes with sparse low shrubs and scattered small conifers, like the Djadochta Formation of Mongolia. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
