A: Cretaceous Chicken does whatever the hell he wants to.
"Then, in the late 1990s, came a scientific bombshell Sinosauropteryx, a dinosaur, with feathers. Preserved in fine-grained lake sediments deposited in the Early Cretaceous, about 128 million years ago, in what is now north-east China, this turkey-sized theropod exhibits clear traces of skin bearing tiny, hair-like protofeathers: dino-fuzz. At least, that is what some researchers claimed, but others were not so sure and wanted more and better evidence. Thankfully, basic economics selling fossils is far more lucrative than tilling the earth solved the problem and the Chinese lake deposits began to produce lots and lots and lots more fossils, among them many beautifully preserved small theropods with feathers. Some bore dino-fuzz, some had rather simple, but clearly feather-like structures and some came with feathers that were indistinguishable from the feathers of early birds fossilised in the same rocks."
