プロンプト全文（英語）

Educational infographic poster of dinosaur evolution across the Mesozoic Era, front-view flat presentation. Layout: a horizontal geological timeline spanning the full poster width, divided into three colored eras: Triassic (252-201 million years ago) in sage green, Jurassic (201-145 Ma) in warm sand, and Cretaceous (145-66 Ma) in dusty blue, with a thin date ruler on top and small extinction-event markers. Along the timeline, flat vector silhouettes of representative dinosaurs are positioned by their time of appearance: Eoraptor, Plateosaurus, Stegosaurus, Allosaurus, Brachiosaurus, Spinosaurus, Velociraptor and Tyrannosaurus rex, each with a name label, size in meters, weight in tonnes and a small prey icon. Color system: earthy fossil tones (#8D6E63, #A1887F), era band colors above, charcoal text (#3E2723) on a pale fossil-cream background (#F4EDE3). Typography: bold display title, clean sans-serif species labels, thin era captions. Background: subtle sedimentary-rock strata texture with faint bone-fossil pattern. Data feel: natural-history museum panel with precise epoch boundaries. Lighting: soft museum spotlights from above, gentle shadows, matte finish. 4k
