On what basis do you make this determination? At no time in development do
birds have more than four manual digits. How does one *tell* that the main
axis digit is IV not III? The whole *point* of the article was using the
main axis to *identify* the digit as IV. If III is the main axis in
dinosaurs sensu stricto then what is left to say that the main digit in
birds is IV?
