The discovery of the Archaeopteryx feathers appears this week in the journal Proceedings of the National Academy of Sciences. The researchers say the sample contains “portions of the feathers are not merely impressions of long-decomposed organic material as was previously believed”. “Instead, they include fossilised fragments of actual feathers containing phosphorous and sulfur, elements that compose modern bird feathers,” write researchers led by geochemist Dr Roy Wogelius of the University of Manchester.
