As of June 2011, the article indicates that the fly wing was found in late Permian beds, based on the cited source which says Upper Permian. However, Natalia von Ellenrieder in her article "Diptera (Mosquitoes, Midges, and Flies)" in Grzimek's Animal Life Encyclopedia: Volume 3: Insects page 357 says that it was from the Upper Triassic. That is quite a discrepancy. It seems that Natalia von Ellenrieder is the one in error, but such an error is disturbing in a reliable source. I checked other sources and they indicate that the fossil was found in the Newcastle Coal Measures, an Upper Permian set of beds. --Bejnar (talk) 21:07, 21 June 2011 (UTC)
