Dinosaur Brain Air Conditioning

July 14, 2017

We are all familiar with the "Head Butting" dinosaurs like Pachycephalosaurus, which I am sorry to say, NEVER WOULD HAVE BUTTED HEADS! 9-inches of solid bone with air passages, gaps, honeycombs or cushion between the top of the skull and the brain. If these Pachycephalosaurids actually set up like a modern day ram and smashed their heads together they would both knock each other out with the potential of killing each other. Not to mention the top of their heads are round! 

As explained by "Dinosaur George", (Look up his podcasts on itunes for some great insight) Take two bowling balls and stand 15 feet apart. Now run and ram these balls into each other. What happens you ask? The rounded surfaces slide off each other to ether side. Imagine doing that with an animal that has very pointed spikes coming out the side of the head under the dome. These animals would most certainly have slid off each other skulls and punctured their eyes if they did this. No animal would risk loosing their sight. 

 

But I digress...The main reason for this post is to tell you literally how cool these dinosaurs brains were. A new discovery of a Stegoceras, a much smaller version of the larger Pachycephalosaurus was found in the 75 million year old rock of Alberta, Canada. The animal almost had a complete skeleton including the skull which is rare for these animals. Nature and time are not kind to this type of bone structure. there have been plenty of these skeletons that had been found with a crushed or no head. 

 

The skull was transferred to Witmer labs in Ohi
