Who was the stupidest dinosaur?

Oh dear; the question is not easy to answer.

The idea of ​​the “dumbest dinosaur” is problematic from a scientific perspective because intelligence is difficult to compare and must always be evaluated in an ecological context.

The Stegosaurus is often mentioned because its brain was very small in relation to its body size - it was about the size of a walnut with a body mass of several tons. However, a small brain does not automatically mean low survivability. Stegosaurus was well adapted to its environment: it was a slow herbivore with effective digestion and protective plates, and probably an effective tail for defense with spines (thagomizer).

Many theropods like Troodon had relatively larger brains, but “simply” built dinosaurs could also be successful. Instead of “stupid” it is more correct to say: different neuronal complexity. Depending on your lifestyle and evolutionary requirements.
