Re: large fossil birds



From: "Michael Habib" <mhabib5@jhmi.edu>

The only catch is that azhdarchids didn't have particularly long wings relative to their size.>

And my point is that the two groups are not directly comparable, given the different evolutionary constraints they inherited. The physics of flight apply equally to both, of course, but they each had to work with what they had. It's my belief that these evolutionary constraints resulted in different physical limits on size for the two groups.
