The image is a vintage illustration of a Megatherium skeleton, an extinct giant ground sloth. The skeleton is depicted in a side view, showcasing its complete bone structure. The skull is detailed with visible teeth, and the spine curves gracefully down to the tail. The limbs are robust, with large claws on the feet. The illustration is done in a detailed, scientific style, with fine lines and shading to emphasize the bone structure. The background is a pale yellow, providing a neutral backdrop for the skeleton. Below the illustration, the name 'MEGATHERIUM. Cuv.' and the number '46' are printed in a classic font.
