No, Pamprodactyl is: having all four toes directed forwards
or (the first being moveable) capable of being so directed.

A New Dictionary of Birds edited by Sir A. Landsborough Thomson
British Ornithologists' Union 1964.

I think you have to make a difference: pamprodactyl is all toes directed
forwards as in Apus apus (a European Swift, don't know the American name for
it), and facultatively pamprodactyl as in Colius, although the Handbook of
the birds of the world state they are pamprodactyl (pg 61) their photographs
and plate clearly show otherwise (pg 67, 69, 73, plate 1, pg 74)! (and not
only the first toe moveable, also the fourth!)

I'm sorry, I can't answer your question on theropod subjects, I'm a birdman.

 My question is this, could some
