Bob the Triceratops


This specimen was excavated on private land in Bowman County, North Dakota in 2003. All of us at Hell Creek Relics have been making progress on Bob ever since and we're within a few months of completion. Bob is from the Cretaceous Period in the Hell Creek formation dated to sixty-five million years old. Bob's skull measures seven feet, two inches from the back of the frill to the tip of the rostrum. It is by far the largest skull we have ever seen. We believe this would be the largest triceratops skeleton out there at twenty-six feet. We have twenty-one out of twenty-four of the largest bones of its body so by bone mass we are well over ninety percent complete. Because it is typical to be missing some of the smaller bones the bone count is still extraordinary at seventy percent. His left femur is four inches longer than the right which is unusual and gives him some definite character.

Bones colored in red are original bones that we have
