No, this is not a late April Fools' joke.
It's real. Some may recognize this as the feathered tyrannosauroid figured back in 2010 in a paper on the ontogeny of
Similicaudipteryx. It was described as being "large", and it
is. How big was
Yutyrannus? About the same size as freaking
Gigantoraptor. Or, for even better perspective, the size of
Albertosaurus and
Gorgosaurus, dwarfing any other known theropod from its environment!
There we go. A large theropod, and a possible tyrannosauroid to boot. Confirmed to have had feathers. More than worth the wait. And remember
this?

(Probably not; I only had a handful of watchers back then.)
I post most dinosaur news here after the end of each month, but, you see, while the
Microraptor feather colors study
almost made me do
this, this discovery
actually made me do it. Several times.
"It weighed in at 1,400 kilograms (3,100 pounds), and was at least 7 or 8 metres in length. That’s 40 times bigger than Beipiaosaurus, the previous record-holder for largest feathered dinosaur (and another Xu discovery)."
Wasn't Sinocalliopteryx the previous record holder?
(I really need to find time to do writeups for Xiaotingia & Samrukia.)
