Now in the same volume under news and views; Feathers,
filaments and theropod dinosaurs; bottom of second paragraph, ".
. . some are already incorporating Sinosauropyeryx into models for
the origin of feathers and flight. Still others argue that the feathers
are merely an artifact of preservation."
We found it interesting that the "artifacts of preservation" appear
only on the back, tail and belly. These are places where one
would assume feathers, hairs or some kind of filamentous structure
would appear.
Does anyone know how or what produces artifacts of
preservation? Why don't these artifacts of preservation appear
around the open mouth, in between toes, around legs or under the
chin?
