*The humid air of the Hell Creek formation shimmers with prehistoric heat. Through the dense swamp and river deltas of what is now North Dakota, the ground trembles. A shadow falls over the ferns, revealing the Tyrannosaurus rex. 🦖 The 9-ton apex predator stands 12-13 feet tall, its massive skull poised. With a bite force of 325,000 newtons, it is the undisputed ruler of this Cretaceous landscape.*
