This was written by Dr Thomas Holtz but I'm still unsure of something - is 
this the ONLY range of movement permited by the semilunate carpal ?? Could 
the hand be moved AT ALL in the dorsoventral plane>?

Was it possible for non-maniraptorans to move their hand inwards at this 
angle - EG Ornitholestes, allosaurids, ceratosaurids(Like Ceolophysis?)

Thanks in advance,
