Quetzalcoatlus in motion.

Use case: scientific-educational
Asset type: full-body paleoart reference for later image-to-3D and matched motion-capture visualization.
Primary request: Create exactly one scientifically informed realistic reconstruction of Quetzalcoatlus lawsoni, the comparatively well-described azhdarchid pterosaur. Follow the anatomical context of the 2021 functional morphology monograph by Padian, Cunningham, Langston and Conway (DOI 10.1080/02724634.2020.1780247), with the smaller Quetzalcoatlus lawsoni skeletal proportions rather than a fantasy dragon.
Scene/backdrop: plain pale warm-gray neutral studio background and ground, a gentle unobtrusive contact shadow only. No environment or props.
Subject/anatomy: a slender walking pterosaur paused at rest on four distinct ground contacts: two hind feet and the three small clawed fingers of each forehand. This is a quadrupedal pterosaur whose front limbs ARE folded wings. The wrist and small free fingers meet the ground; the enormous fourth wing finger is folded upward/backward along the side of the body and NEVER supports weight. Show that anatomical continuity clearly on both wings. A huge very long narrow toothless spear-like beak, relatively small skull at the beak base, a long fairly straight stiff-looking neck held steeply upright/sloping forward, compact small torso, long slender limbs. The beak extends nearly horizontally toward the right. The long fourth wing finger folds back/up along each flank; a narrow, continuous skin membrane remains folded along it and the flank. Wings fully folded, no open flight wing. Each hand has three small separate clawed fingers beside the folded fourth digit. Both hind feet are small, long-toed feet. Fine short fuzzy pycnofibres on neck and torso, bare leathery wing membranes, restrained natural warm gray/buff body, darker gray-brown membranes and muted ivory/gray beak. Biological surface detail without feathers. Soft tissues and coloration are artistic reconstruction, not certainty.
Composition/framing: landscape 16:9, approximately 1600x900. Entire animal uncropped, comfortable wide margins on every side, full neck and every bit of beak in frame. Nearly exact lateral side view facing RIGHT, with only a very slight three-quarter angle to separate the near and far limbs. Near and far hands and near and far feet must appear as four spatially separated ground contacts, no hiding one behind another. Natural paused walking stance with slight offsets of near/far appendages, all four supporting points planted. Camera far enough away for the whole animal, little perspective distortion. The torso, folded wing fingers, membranes, long neck and all four contacts must be legible.
Style/medium: museum-quality realistic paleontological reconstruction, softly lit detailed 3D-like natural surface rendering.
Constraints: only one animal, no costume or tracking markers yet; no labels, text, watermark, humans, scale bars, measurements or anatomical diagram overlays.
Avoid: mammalian forelegs, bird arms, bird feathers, generic bat body, bat ears, dragon spikes, extra limbs, extra toes on the hands, fully spread wings, weight on a wingtip, on the wing finger or on an elbow, disconnected wing membranes, crouching caricature, cropped beak, decorative environment.
