I've never heard anyone suggest this level of intelligence in dinosaurs before, outside of fiction. Interesting, but there's no detail here.
As fearsome as a pack of Velociraptors would have been, no theropod eclipses the King of Dinosaurs: T. rex. Over a century ago, Osborn’s sawed-up skull hinted that T. rex had a fairly large brain and more recent CT work by Dr Larry Witmer of Ohio University confirms it.
In fact, not only was T. rex roughly as intelligent as a chimp, but it had enormous olfactory bulbs that imparted a strong sense of smell, elongate and looping inner ear canals that coordinated rapid eye movements and quick reflexes, and an elongate cochlea that could hear low-frequency sounds. If a 13-metre-long, 7-tonne, bone-crunching predator wasn’t scary enough, its brainpower and sensory acumen ensured that T. rex was the biggest, baddest predator that ever lived.
