What’s the dumbest dinosaur and what’s the smartest dinosaur?

— Kata Rivera, aged 5, Miami, FL


Mamenchisaurus was a plant-eater 70 feet long with a brain the size of a ping-pong ball. Comparing brain to body size, it was the stupidest backboned animal ever.

Troodon was the smartest dinosaur. It was a meat-eater the size of a third-grader. It’s brain was as big as an avocado pit. Your brain is the size of a grapefruit.
