One of the exhibit's centerpieces is the Yutyrannus â a 1-ton cousin of the Tyrannosaurus rex discovered in China in 2012. I guess we’ll have to wait and see—according to an interview with Xu on the Nature podcast, this research is already underway. A smaller, earlier theropod called Juravenator was preserved with traces of dinofuzz, and there have been rumors that this dinosaur might turn out to be something other than a coelurosaur. A newly discovered titanic tyrannosaur is the biggest feathered dinosaur yet, reaching up to 30 feet (9 meters) long and weighing more than 3,000 pounds. The report is a red flag to Hollywood and some scientists who get wobbly legs thinking something as ferocious as T. rex might have been packaged with a soft downy overcoat.

Xu is somewhat of a rock star among dinosaur-hunters. This feather-accessorized dino came along about 125 million years ago, 60 million years before T. rex. Killjoy that I am, I loved the idea that the dinosaur made it all the more likely that other big tyrannosaurs were at least partly covered in filamentous protofeathers. Giant tyrannosaurs with feathers was a respectable idea, but there was no direct evidence.

Their huge bodies lose heat very slowly, and they don’t need the insulation that their smaller cousins do.
