Ancient Melanosomes, Beta-Keratin Found in Fossilized Feathers of Early Cretaceous Bird

Nov 25, 2016

  • An international team of paleontologists has found evidence of beta-keratin and melanosome preservation in a 130-million-year-old specimen of the Early Cretaceous bird Eoconfuciusornis. Eoconfuciusornis, a genus of crow-sized primitive birds from the Early Cretaceous Dabeigou and Huajiying Formations of China, dating from 135 to 125 million years ago, are the earliest birds to have a keratinous beak and no teeth, like modern birds. http://cdn.sci-news.com/images/2016/11/image_4398_1-Eoconfuciusornis.jpg
