How It Works-Book Of Dinosaurs

DID YOU KNOW? (^) Troodon could run after its prey at 30kmh
By comparing the size
of its brain to the size of
its body, then looking at
similar-sized animals
today, scientists were
able to work out that
this was a clever dino
A smarter
dinosaur
Most dinosaur
brains were as small
as walnuts, but the

much bigger. It used

than the Troodon, so the fact
that its brain was still much
smaller means it was much
less intelligent
