It was almost certainly a browser, and from its body design one can probably assume it lived on low-lying vegetation. It was big - 15-20 feet long, about 10 feet tall, and weighed about 3 tons... yet the brain in its head weighed less than 3 ounces. It apparently had a swelling of its spinal cord in the vicinity of its pelvic girdle that was about 20 times the size of the brain in its head, the function of which is food for speculation. Was it a second brain? Not in the most common meaning of the word. None of the senses were routed through it -- sight, smell, hearing, etc. were restricted to the brain in its head... if it had a central nervous function it was probably to aid in the control of the animal's huge muscles.
T. rex didn't come along until the late Cretaceous, about 80-million years later when Stegosaurus was long gone.
