"Nova: The Four-Winged Dinosaur" addresses the issue of the femoral

theropodan ancestry of birds for those who have been out of the loop
last 40 years.
Interestingly enough, while the model used by Norell, Ellison, and
Brougham seems to involve rather less fudge factor, both teams tried to
force the hindlimb feathers to point laterally in some fashion - a
starting assumption which may not be very robust.
