Stygimoloch
(STIG-i-MOL-ugh)
Stygimoloch means "demon from the River Styx"
Stygimoloch was 8 feet long and 3 feet tall at the hips.
He weighed 50 pounds.
Stygimoloch was a 2-legged plant eater with a thick,
narrow high domed skull bristling with bony horns
and spikes, probably brandished by rival males.
Stygimoloch had a soccer ball sized head with a
large dome which is actually the top of the skull.
The skull was very thick. It would seem as if this dinosaur
would have a large brain but much of the skull was pure bone,
this made the dome extremely strong.
But this left little room for a brain.
There were also spikes around the dome.
Male Stygimoloch used the dome to fight against each other.
But Stygimoloch was a plant eater.
Stygimolochs lived in herds.
Stygimoloch lived in present day Montana, and Wyoming, USA.
He lived during the late Cretaceous.
