The fact that an animal weighing over 4.5 metric tonnes (5 short tons) could have a brain of no more than 80 grams (2.8 oz) led to the idea that dinosaurs were unintelligent, an idea now largely rejected.

Did T Rex have a small brain?

What animal has the biggest brain?

sperm whaleThe sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don’t necessarily make a smarter mammal. But as mammals evolved, many groups, from Primates to Carnivora, have shown independent increases in brain size.
