Long-snouted ‘Pinocchio rex’ called new breed of tyrannosaur

Its nickname may sound funny — “Pinocchio rex” — but it probably would not have been wise to laugh at this strange, long-snouted cousin of the famous meat-eating dinosaur T. rex, as it easily could have eaten you alive.

Scientists have identified a new member of Tyrannosaurus rex’s family, a beast named Qianzhousaurus sinensis that was up to 30 feet (9 meters) long and stalked China at the very end of the age of dinosaurs.

It differs in some significant ways from other members of the carnivorous group of dinosaurs known as tyrannosaurs, especially with a skull far more elongated than that of T. rex.

“It’s a new breed of tyrannosaur, with a long snout and lots of horns on its skull, very different from the short-snouted, robust, muscular skulls of T. rex. So it tells us that tyrannosaurs were more ecologically variable than we previously thought,” said paleontologist Steve Brusatte of the University of Edinburgh in Scotland, one of the researchers.

Its elongated snout prompted researchers to nickname it Pinocchio rex.

Qianzhousaurus lived about 66 million years ago, not long before an asteroid hit Earth and wiped out the dinosaurs and many other creatures.

“It would have been one of the last surviving dinosaurs, and this species may have even witnessed the asteroid impact,” said Brusatte, whose study appears in the journal Nature Communications.

Qianzhousaurus was smaller than T. rex, which lived at the same time in North America, measured about 40 feet (12 meters) long and was the largest known land predator ever. Even though it still had the “toothy grin” of T. rex, the unique snout of Qianzhousaurus and its more slender build suggested it favored different types of prey than conventional tyrannosaurs, the researchers said.

“It was still a big boy,” Brusatte said. “And it still had a long mouthful of sharp teeth. You wouldn’t want to run into it. It is something of a runt compared to T. rex, but T. rex was the baddest predator of all time.”

The beautifully preserved fossil was found by workmen at a construction site in Jiangxi province in southern China.

Its genus name, Qianzhousaurus, honors a nearby city. Its species name, sinensis, pays homage to China.
