Would a Tyrannosaurus Rex fit inside of the Dove Library?
Answer
Yes, a Tyrannosaurus Rex would be able to fit in the Dove Library, although s/he might not be able to get through the front door.
Our great hall dimensions from staircase to balcony (~ 35 feet), entrance to Information Desk (~ 25 feet), ceiling height (~ 35 feet) would accommodate a full-grown tyrannosaurus (approximate dimensions of 43 feet long and 13 feet tall at the hips).
