Pawpawsaurus was a medium-sized armoured dinosaur that lived in what is now Texas, USA, about 100 million years ago. It had a complete skull with bony eyelids, which is rare among its relatives. Scientists used CT scans to study its brain and inner ear, learning how it sensed the world.12

1

Pawpawsaurus is the only nodosaurid known to have had bony eyelids, which are common in ankylosaurids.1

2

Its brain was about 96 millimetres (3.8 inches) long and 35 millimetres (1.4 inches) wide, which is 30% of the skull length.1

3

CT scans revealed that Pawpawsaurus had hearing similar to modern crocodilians, meaning it did not hear very well.1

4

Its sense of smell was more powerful than many meat-eating dinosaurs of its time, thanks to its large nasal cavities.1

5

The large nasal cavities may have helped cool blood going to the brain, find food, or detect danger.1

6

Pawpawsaurus lived about 105 to 100 million years ago during the Early Cretaceous.15

7

The only known specimen is a complete skull, which was found in 1992 by Cameron Campbell.1
