During a blip in time in the late Jurassic, a dinosaur that weighed no more than a chinchilla flung itself from tree to tree, spread its wings and tried to soar. In theory, it sounds beautiful — an early attempt at flight before birds figured out the blueprint.
In practice, it was chaotic.
The dinosaur, Yi qi, only barely managed to glide, stretching out and shimmying its skin-flap, downy-feathered wings in a valiant attempt at flying. “It was rocketing from tree to tree, desperately trying not to slam into something,” said Alex Dececchi, a paleontologist at Mount Marty University in South Dakota. “It wouldn’t be something pleasant.”
Unsurprisingly, Yi qi is not an ancestor of modern birds. It went extinct after just a few million years, presumably doomed by its sheer lack of competency in the air. In a study published Thursday in the journal iScience, Dr. Dececchi and other
