Re: John Bois on Armadillos at the K/T!

Hi guys, for some time I've been interested in the observation that there
don't appear to have been many small pterosaurs by the end of the Cretaceous
-- and there don't appear to have been any large birds.  I've wondered about
the effects of mutual competition in that regard, especially since in the last
month, I've run across some indicators for perhaps three giant pterosaurs in
the size range of northropi, all azhdarchid and all seemingly larger than the
probable maximum for birds.  What is your take on interactions with regard to
size?
