Câu hỏi: ¿A qué especie pertenece el anquilosaurio?
 Ngữ cảnh: In 1906, an American Museum of Natural History expedition led by paleontologist Barnum Brown discovered the type specimen of Ankylosaurus magniventris (AMNH 5895) in the Hell Creek Formation, near Gilbert Creek, Montana. The specimen (found by collector Peter Kaisen) consisted of the upper part of a skull, two teeth, part of the shoulder girdle, cervical, dorsal, and caudal vertebrae, ribs, and more than thirty osteoderms. Brown scientifically described the animal in 1908; the genus name is derived from the Greek words αγκυλος/ankulos ('bent' or 'crooked'), referring to the medical term ankylosis, the stiffness produced by the fusion of bones in the skull and body, and σαυρος/sauros ('lizard'). The name can be translated as "fused lizard", "stiff lizard", or "curved lizard". The type species name magniventris is derived from the tiếng Latinh: magnus ('great') and tiếng Latinh: venter ('belly'), referring to the great width of the animal's body.
