Stegosaurus had a very small brain compared to its body, but it still survived for millions of years.1

The plates on its back were probably used for display or to control body temperature, not for fighting.1

Its tail had spikes, and scientists think Stegosaurus used them to defend itself from predators like Allosaurus.1

Stegosaurus had small, peg-shaped teeth that were not good for chewing, so it probably swallowed plants whole.1

It could probably only eat plants that were about 1 meter (3 feet) above the ground, unless it stood on two legs.1

Stegosaurus is the state fossil of Colorado, USA, since 1982.1

Scientists are not exactly sure. The plates may have been used for display, to recognize each other, or to regulate body temperature. They were probably not used for fighting.3 1

?Did Stegosaurus have a small brain?

Yes, Stegosaurus had a very small brain compared to its body. Its brain was around the size of a plum!3 1

Dëgg: Scientists now think that space in the hips was just for storing energy, not for a second brain.1
