Wow! The BioOne site also has American Zoologist 40/4, the evolution of feathers extravaganza that includes the Martin/Czerkas paper. The Hutchinson et.al. theropod locomotion paper is here too. I know what I'm doing tonight. Find the volume here: http://www.bioone.org/bioone/?request=get-toc&issn=0003-1569&volume=040&issue= 04
