Below the cervical vertebrae are the thoracic vertebrae. These bones each attach to one row of ribs from the rib cage. The thoracic region of the spinal column is often much larger in large four-legged mammals, such as horses and elephants because their stomachs are far too heavy to be supported by the muscles of their abdomen so their rib cage extends further down body.

And stomachs of herbivores will be large.
