• The article is new enough and long enough, with use of the type description and several media references. I have reservations about the statement that Maniraptorinae as a group is called the "four winged dinosaurs" as the last sentence in the introduction seems to suggest. Also the bbc reference does not support the hook as stated here. it only states that Changyuraptor was the largest flight capable dinosaur with hind leg feathering.--Kevmin § 08:29, 21 July 2014 (UTC)

• Kevmin, thank you for your comments. Firstly, I have amended the last sentence of the introduction to remove the inference which you rightly pointed out - Micropraptorinae contain "four-winged" species, but not all microraptorines are four-winged. Secondly, the BBC article quotes "Measuring 132cm from its snout to the tip of its tail feathers, it is the largest four-winged dinosaur ever discovered - longer than an eagle or an albatross today..." which supports the hook. As such, this Nature article is titled "Four-winged dinosaurs from China" which indicates that "four-winged" is a legitimate term. I hope this addresses your second concern. Thanks, AshLin (talk) 04:01, 3 August 2014 (UTC)

• It only partly addresses the comments, as birds are classified, phylogenetically at least, as derived theropods, this means that Changyuraptor is/was not the largest flight capable Dinosauriform. Also it BBC quote is stating that Changyuraptor is the largest of the four-wing style flyers, not that Changyuraptor was the largest flyer and happened to be a four winged form also. Currently the hook suggests the latter, rather then the former.--Kevmin § 06:53, 3 August 2014 (UTC)
• Also the last sentence of the opening paragraph now seems to contradict the opening of the Microraptoria article which notes larger genera are known.--Kevmin § 07:02, 3 August 2014 (UTC)

• Thanks for further comments Kevmin.
  • Firstly, the last sentence of the introduction to Changyuraptor has been amended to be absolutely specific --as per the original reference which says...
    • Abstract - "We report the discovery of the largest known ‘hind-wing’ paravian".
    • Article - Changyuraptor yangi is the second unquestionable dromaeo-saurid (after Microraptor) to possess ‘hindwings’, and by far the largest of all the known ‘four-winged’ dinosaurs.
  • Secondly, the original hook is depreciated and Alt 1 & 2 suggested instead.
• Hope this addresses the issues satisfactorily.

• Everything is looking good to go now! The article is free of any coflicts that I can see, and reflects the current taxonomies well. Referecnes behind paywall taken afg, length and newness still good, no policy issues found.--Kevmin § 16:38, 3 August 2014 (UTC)
