The refs just keep pouring in...
This batch is from _Neues Jahrbuch fur Geologie und Palaontologie
Kaiser, G.W. Alternative origins for flight in birds. pp. 27-39.
I think this one warrants putting the abstract here:
"Three origins for flight in birds are discuseed in terms of adaptive
scenarios. The discovery of feathered but flightless dinosaurs in China
suggests that many of the adaptations in birds, currently considered as
components of flight, might better be considered as requirements for the
success of feathers and the development of feathers may well have been a
more important event in bird evolution than the development of flight. The
existence of an array of potential ancestors with feathers and the success
of large groups of birds without volant representatives suggest that flight
might have evolved more than once."
...and the inevitable rebuttal (which gives a clue as to the theme of the
Pfretzschner, H.-U. Is aquatic habit really an alternative origin for flight
in birds? pp. 41-43.
Larsson, H.C.E. and Gado, B. A new Early Cretaceous crocodyliform from
Niger. pp. 131-141.
