Whose brain weighs the most a gorilla a human or a triceratops?

A gorilla's brain weighs more than a human's brain, typically around 400 grams compared to an average human brain of about 1,300 to 1,400 grams. However, the brain of a triceratops, a dinosaur, is significantly smaller, weighing only about 300 grams. Therefore, the human brain is the heaviest among these three.
