Larger species have a more vertical ilium, bringing the sacroiliac joint (and with it the weight of the trunk) closer to the hip. Smaller species have an oblique ilium. The dog has a stout cord extending between the sacrum and lateral ischial tuberosity, this is not present in the cat. In ungulates, the '''sacrosciatic ligament''' expands to a broad sheet. | Larger species have a more vertical ilium, bringing the sacroiliac joint (and with it the weight of the trunk) closer to the hip.
