INTELLIGENCE
T. rex was a relatively smart dinosaur. Although the ratio of brain size to body mass was very small for T. rex, it was larger than most other dinosaurs. T. rex's brain was larger than the human brain, but the cerebrum (the part of the brain that we use to think) was tiny. T. rex's brain was long and almost cylindrical in shape.

Only very advanced theropods, like the dromaeosaurid dinosaurs (for example, Deinonychus and Velociraptor), were probably smarter than T. rex.

T. rex probably ranked close to the carnosaurs in intelligence.



Care of the Young
There's no fossil evidence that any theropods (meat-eaters like T. rex) took care of their young, but they may have taken care of the hatchlings for a short time in that vulnerable time right after hatching, like most birds do.
