"I suspect that the sudden environmental devastation caused by the impact was so severe that it killed off many, many species on land, and perhaps birds were the one dinosaur group able to make it through because they were smaller, could fly, and could grow fast," Brusatte explained, adding that it's still a mystery as to why so many bird-like feathered dinosaurs, like Velociraptor, did not survive.
Pinocchio rex, at least, lives on today in the dinosaur record books, via its well-preserved remains.
Both Thomas Carr, an associate professor of biology at Carthage College, and Thomas Williamson, from the New Mexico Museum of Natural History and Science, are leading experts on tyrannosaurs. They told Discovery News that they believe that Pinocchio rex is an important find.
Carr said he was curious about "how the long snout evolved in the first place," and that he looked forward to more discoveries that could answer this and other questions concerning the dinosaur.
Williamson mentioned that "tyrannosaur evolution was even more complex and interesting than previously thought," especially given that tyrannosaurs with long and shorter snouts co-existed. This suggests that they must have lived and hunted differently -- somehow not eating each other to death before the asteroid hit.
