Some believe the animal’s arms were an evolutionary leftover—like the pelvic bones of a snake—or served non-predatory purposes like helping it grip a mate. During this rapid growth phase, a young T. rex would gain an average of 600 kg (1,300 lb) a year for the next four years. By comparing this to the expected value for a typical reptile scaled up to the size of a T. rex, I found this volume fell very close to the expected value for a typical reptile, showing again that the T. rex was not bird-like in brain size (Figure 2). The brain was long and in the shape of a cylinder. Tyrannosaurus rex brain was about the size of a gorillas brain.

The encephalic volume (brain size) of the adult T. rex was estimated by submerging the cast in water. Stegosaurs and sauropods had the smallest brain-to-body ratios, whereas theropods like T. rex had much larger brain-to-body ratios. The endocast showed that the brain was indeed small: relative to body size, maybe the smallest among the dinosaurs. The brain was long and in the shape of a cylinder. Brain endocasts may not be able to give us a true measure of intelligence, but we do see that many dinosaurs had different brain sizes relative to body size. T-rex Brain (cast).
