Recently, a 163-million-year-old therapod dinosaur was discovered in China: Ambopteryx longibrachium. With bat-like wings that would have allowed it to glide. It was about a foot long and weighed less than a pound. It is in a family of scansoriopterygid dinosaurs that are the ancestors of birds. (its wings were membranous rather than feathered)
Lots to write about: a present-day mama-sized Ambopteryx attacks Louisville during the Derby, but the race must go on!
