The research of dinosaurs was shocked recently to find that there was an even later period of dinosaurs that possibly had contact with humans...
They found a skeleton deep within the desert and have called it...The Staggosaur(see skilled artists recreation above).
Shockingly the recently exhumed skeleton has a skull that was almost nine inches thick in all directions. with a brain cavity big only enough to house a few pellets of bird shot. It is believed that he might have wandered into the desert in search of water.

Hope you dig.
