Concerning Longisquama, this week I read here in Germany short reports in two
news magazines and one newspaper about it. All of them told the "first
feather found" story as proof for the non dinosaurian origin of birds. One of
the reports didn't even mention that there are doubts about the validity of
the observations and conclusions made by Ruben! Seems to me like Ruben is a
master in public relations.
Concerning BANDits (Bird Are No Dinosaurs), it looks like that these
scientists try to find a killer character, which would make a dinosaurian
ancestry implausible. E.g. respiratory turbinates, 2-3-4 digital formular and
hepatic piston respiration fall into this category. Furthermore they state
that some characters like feathers could have developed only once. And of
course it's them who have found the real thing.
For me it's more interesting to see these "wings" of Longisquama confirmed as
integumentary structures, of whatever kind. Together with these chinese
dinosaurs like Sinosauropteryx it would show how versatile reptilian
integument is, not just bare scales and scutes.
