A dinosaur called Yi qi appears to have lifted a page from pterosaurs’ flight plan.
Protruding from each of the newly discovered dinosaur’s wrists was a weird rodlike bone that may have attached to a fleshy wing that helped the dinosaur glide or fly, researchers report April 29 in Nature.
“We’ve never seen anything like this in a dinosaur before,” says paleontologist Sarah Werning of Stony Brook University in New York. “It’s almost like this dinosaur was pretending to be a pterosaur.”
Pterosaurs, flying reptiles that lived at the same time as dinosaurs, had fleshy wings supported by a short bone called the pteroid bone and a long finger bone.Y. qi’s rodlike bone is similar to the pterosaur’s pteroid bone but is longer. Unlike pterosaurs’ shorter wing-supporting bone, Y. qi’s bone probably
