This is a vintage illustration of a Paleotherium magnum, an extinct mammal. The animal is depicted in profile, standing on all four legs. It has a large, robust body with a somewhat horse-like shape, but with a distinctive, elongated head and a blunt snout. The coat is covered in small, dark spots. The legs are relatively slender, and the feet appear to have multiple toes. The illustration is done in a simple, linear style, with shading to give the animal some volume. Below the illustration, there is text identifying the animal as 'PALAEOTHERIUM magnum. Cuv.' and the number '41.' The background is a faded, beige color, giving the image an aged appearance. The overall style suggests a scientific illustration from the 19th century.
