So, was the big bad and considered not-to-smart Tyrannosaurus Rex actually smarter than has been thunk for a long time in paleontological circles?
Maybe.
The T. rex may have been a lot smarter than you thought
"Extrapolating from emus and ostriches, [Vanderbilt neurologist/biologist Suzana] Herculano-Houzel estimated the T. rex’s cerebrum had as many as 3 billion neurons, comparable to a baboon’s brain. Another terrifying carnivorous dinosaur called the Alioramus, meanwhile, had over 1 billion, similar to a capuchin monkey.
If the T. rex’s cognition approached that of a baboon’s, the dinosaur may have been capable of using tools and passing down knowledge through generations, Herculano-Houzel said."
Hmm ... a tool-using gigantic dinosaurian predator? That's not scary.
See?
