Flipping the Semi-Bird
Changyuraptor is the largest four-winged, feathered dinosaur found yet:
The meat-eating creature, called Changyuraptor yangi, had exceptionally long tail feathers, the longest feathers of any dinosaur, at one foot in length (30 cm). It had feather-covered forelimbs akin to wings as well as legs covered in feathers in a way that gave the appearance of a second set of wings.
Changyuraptor is not considered a bird but rather a very bird-like dinosaur. It illustrates that it is not always easy to tell what is and is not a bird. It measured a bit more than 4 feet long (1.3 meters) and weighed roughly 9 pounds (4 kg).
“Animals like Changyuraptor were probably not engaged in powered flight like modern birds. However, Changyuraptor and dinosaurs like it could flap their wings and certainly had large feathered surfaces on both their forelimbs and hind limbs,” Turner said.
“So this does raise the possibility they could glide or ‘fly’ in a primitive sort of way. The way I like to think of it is: if you pushed them out of a tree, they’d fall pretty slowly,” Turner added.
If you want to try pushing the large meat-eating dinosaur out of a tree, be my guest.
