The Tyrannosaurus rex at London’s Natural History Museum has gotten in on the holiday sweater trend. T-Rex’s sweater features a fellow member of the extinct creature club, a Diplodocus. Getting the T-Rex ready for the holiday season wasn’t easy. The animatronic dinosaur is 13-feet-tall and 23-feet-long, which is about three-quarters the size of what the dinosaur could have been when it was alive.
