2. Once Mistaken for Knee Caps
This just had to happen! With such a thick bone, who would have guessed it to be a head for the first time! Interestingly, dinosaurs don not have kneecaps at all.

Micropachycephalosaurus, a cousin of Pachycephalosaurus (excuse me for too many tongue twisting names in one sentence!) has the longest name!

4. Still Injured

5. Group People … Oh Sorry, Dino
Pachycephalosaurus liked to dwell in groups and live in the coastal regions. T. Rex and Pachycephalosaurus lived in North America and therefore it was necessary for Pachycephalosaurus to take a shelter from its predators.

6. No Battles
It was once thought that Pachycephalosuars once rammed each other like modern day big horned sheep, however this would most likely kill the animal since the skull is not as strong as it seems to be.
