HISTORY
Sir William was found in 2002 by Walter Stein while scouting with TPI.

Mike Triebold was on the next ridge, about 100 feet away, working on some preserved Pachycephalosaurus skull parts. Bill hollered that he was done there and moving on to the next butte. Mike looked up and said “No, you still haven’t looked higher up. See that ridge above your head? Go along the ridge at that level before you move on.” As soon as Bill moved up to that high level, he saw the dentary of what would become known as Sir William at his feet. Mike had thought about going over there and scouting the top of the butte himself, but was hopeful the Pachycephalosaurus material would lead to something significant (it didn’t) and it was hot and late in the day.

The team thought it was a juvenile rex at the time but figured out later that it was in a small set of Judith River outcrops nestled among a large swath of Hell Creek formation. It set the timeframe of the animal back about 9.3-13 million years, thus changing the identification from a T. rex to Teratophoneus.

FAST FACTS

• The hand was bitten off and dislocated, likely by a crocodile like Deinosuchus. Something bit into and crushed the radius/ulna and twisted the elbow out of its socket. Lots of healing happened that we can see in the gnarly bone that’s left over. If there had been a veterinarian in the late Cretaceous, this animal could have saved itself a lot of pain.

• This is either a new species of Teratophoneus or even a new genus entirely. More study is needed. It’s a lot bigger than the few Teratophoneus already found.

• The big “lacrimal horn” in front of the eye socket is gigantic. Look for the gnarly bump in front of its eye.
