Extinct Animals Ornamental Portrait Grid

2x2 grid, 16:9, 4 extinct animals that ruled their kingdom. Generate a monochrome ornamental portrait of TOPIC. Rules: infer the canonical silhouette and most recognizable internal features of TOPIC; segment the subject into meaningful visual regions; fill each region with a different but harmonized ornamental system; ornaments must follow local contours, anatomy, surface direction, and form; use spirals, dots, hatching, concentric rings, filigree, micro-glyphs, geometric motifs, and flowing linework; embed topic-relevant symbols or letterforms subtly inside the pattern language; use pattern density instead of conventional gray shading; preserve crisp white negative-space highlights at the most important focal features; maintain strong silhouette readability from a distance; near view should reveal hundreds of intricate micro-details; black ink on white ground, no color, no hard-coded motifs.
