message: The scale image appears to be in discord with the scale image in the H. sparsa article (http://en.wikipedia.org/wiki/File:Burgess_scale2.png). Specifically, in the scale image for this article, the H. sparsa is labeled as P. gracilens, and the P. gracilens is labeled as H. sparsa (http://upload.wikimedia.org/wikipedia/commons/2/2f/Burgess_scale.png).

message: I deleted the word "curious" from the first sentence today for being unencyclopedic. Another user then inserted "enigmatic", asking in the edit summary if "enigmatic" is more encyclopedic than "curious". I'm going to revert. In the case anyone disagrees, please post here first.

message: The taxonomic classification given here for Dinocarids is not in agreement with the one in Wikispecies. Note that Dinocarida is there described as a phylum, not a class; and that Opabinida is given as one of the order (presumably the one for Opabinia species), not Radiodonta. Does anyone know which one is right? Any new information on current taxonomical classification of Opabinids? (My guess is the Wikispecies people know best; if nobody answers, I'll change the classification to match what I see there.) 
Another question: two sources (http://www.fossilmuseum.net/Fossil_Sites/Chengjiang/Chengjiang-Biota.htm and http://palaeo.gly.bris.ac.uk/Palaeofiles/Lagerstatten/chngjang/) do not mention Opabinia species in the Maoshantian shales (with which Wikipedia agrees: see Maotianshan shales), but one does (http://wwwalt.uni-wuerzburg.de/palaeontologie/Stuff/casu30.htm). Does anyone know who is right? If there are Opabinidae in the Maotianshan shales, then I suppose the information should be here (as it currently is); but if there aren't, then it should be deleted from here. (My guess is the source that does mention Opabinia is wrong -- note that it still mentions Opabinia under Arthropods, and that it gives bibliographic sources for most species, but not for Opabinia.) --Smeira 00:34, 4 January 2007 (UTC)

replies: text: The sources say that the maximum length of Opabinia is 101 millimeters.  Do you have a source that says 50 centimeters?--Mr Fink (talk) 16:50, 11 December 2013 (UTC)

message: Hey, I agree that this article is ready to run for GA!  Although you do need to sort out the "notes" and "references" sections.  Great work!!  Martin (Smith609 – Talk) 19:10, 26 August 2008 (UTC)

message: Is there a slightly better version of the 'comparative sizes' image under 'History of discovery' - the text is unreadable on expansion. Jackiespeel (talk) 13:42, 29 March 2016 (UTC)
replies: text: I can (barely) read the text in the image, mostly because I'm using a desktop computer with a large screen.  , I'm presuming that you're reading from a tablet or similar handheld device?  Perhaps we could ask  if he could modify the text?--Mr Fink (talk) 15:06, 29 March 2016 (UTC)
replies: text: I was using a computer too (and clicking on the image): the text is readable now.
