Pteranodon is a large flying reptile. When it spread its wings, it could reach from the front to the back of a school bus. It did not have feathers, but rather had a basal type of integument along the same lineage from which feathers evolved, called pycnofibers. Pycnofibers were very hair-like in appearance and, like hair, were made of keratin.
