Describing and Feathers

The most important paper is always the describing paper. Fortunately that is available online as a pdf, which is wonderful because it is already free and something that can be shared amongst the interested individuals out there in the world. Another article, free online as a Nature article by Lucas Laursen discusses the importance of the discovery of feathers on this dinosaur. Feathers on this dinosaur completely pushes back the age of feather development in dinosaurs and absolutely changes the story of feather development in all dinosaur lineages. The article mentions the quill attachment sites and briefly discusses them, but does not go into depth on them.
