As a 4yo

Tufts of feathers adorn the T. rex’s head and run down its spine. It’s widely accepted that many dinosaurs had feathers and bird-like features. Indeed, Norell was part of the team that discovered the first fossilized remains of a feathered tyrannosaur (Dilong paradoxus) in China in 2004. However, putting plumage on the adult T. rex is still considered by some to be an inferential leap.

“No one has found a fossil feather on a T. rex, but we’ve found more relatives of T. rex with feathers, so we can infer it,” explained Norell.

“We know some of what it ate because of the poop; 50 percent of it was bone,” explained Jasmina Wiemann, a molecular paleobiologist and doctoral student who contributed to the exhibition. Thanks to x-ray fluorescence and microprobe analysis, we know T. rex chewed up and swallowed the bones of its victims.

...

It had a larger brain than previously thought, with a more pronounced olfactory area and large eyes, indicating that it had an acute sense of smell and sharp vision. (So much for hiding from the dinosaur by standing still.)

...

However, from what they can determine from T. rex’s overall cranial structure, it probably didn’t have a Jurassic Park lion-like roar, but it also didn’t chirp like a bird. Best guess is something akin to a crocodile’s bellow.
