While obviously the title of the blog covers birds, they get rather short shrift on here as I try to focus on the Mesozoic archosaurs. However, even this definition doesn’t rule out all the various birds that lived in the Jurassic and Cretaceous. Here then are a couple of them, first off (above) a not-that-great photo of the not-that-great holotype specimen of Jeholornis.
Secondly (above and below) the near ubiquitous Confuscisornis. I’ve seen well over a hundred specimens of this without having troubled many of the museums in Liaoning that have extensive birds collections so it’s a pretty safe bet that there are several hundred specimens of this in China and probably well into the thousands when private collections are taken into account. Although I’ve not heard of anyone actually trying to crunch the numbers, I’d not be surprised if it was one of the most common tetraopods from Liaoning (certainly apart from a couple of the amphibians and near infinite hyphalosaurs) and there seem to be few museums now, inside or outside China, that don’t have a specimen or two somewhere.
