Due to the lack of transitional fossils, little is known about how that modification took place. In living birds, the tail ends in a compound ploughshaped element termed pygostyle that attaches the fan-shaped tail feathers, forming an indispensable flight apparatus. Based on comparative anatomical, histological and electrical scanning analyses, Wang et. al. suggested that the plough-shaped pygostyle and the tail fanning is evolutionally decoupled in the early avian history, which challenges the long-standing theory that these two features are coevolved. A plough-shaped pygostyle is distributed widely in Ornithuromorpha. Therefore, the rare occurrence of this structure in some enantiornithines is the result of convergence, as confirmed by a few other fossil birds, further highlighting that the early avian evolution is characterized by parallelism., correspAuthors=null, authorNote=null, correspAuthorsNote=10.3981/j.issn.1000-7857.2018.23.004, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=AsW7GFu1rqo8ASQvt7PdRA==, pdfFileSize=1770497, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
