Theropod forearm musculature

Does anyone know of any work that has been done on the musculature of the
theropod forearm using muscle attachment sites, tendon scars etc? If so,
how close does this musuclature come to that of _Archaeopteryx_ and modern
birds, particularly with regard to the M. biceps brachii, Pectoralis Major
and the Supracoracoideus muscles.
Any pointers to the literatue on this topic will be gratefully received.

Many say it was a mistake to come down from the trees, some say
the move out of the oceans was a bad idea. Me, I say the stiffening
of the notochord in the Cambrian was where it all went wrong,
it was all downhill from there.
