It's currently Anchisaurus sinensis, since Gyposaurus was synonymized with 
Massospondylus by Cooper in his African prosauropod implosion paper

Cooper, M. R., 1981. "The Prosauropod Dinosaur Massospondylus carinatus Owen 
from Zimbabwe: Its Biology, Mode of Life and Phylogenetic Significance," 
Occasional Papers of the National Museums and Monuments, Rhodesia 6(10): 
689â840.

Ultimately Anchisaurus sinensis may be synonymized as a juvenile of some 
other Chinese prosauropod or may be made the type species of a new genus. I 
don't think there's much evidence that Anchisaurus occurred in both China and 
North America during the Early Jurassic.
