Anewborn human baby has a bigger brain than most adult dinosaurs would have had. Dinosaurs walked the Earth until about 65 million years ago, when they suddenly went extinct – nobody knows exactly why, but possible theories are that a meteorite hit the planet and the resultant tremors and tsunamis caused the mass die-off, that dinosaur bodies got too big for their brains to sustain, or that mammals were eating their eggs, causing the population to become unstable.
