About Szechuanosaurus:

Not a whole lot is known about Szechuanosaurus, except that this Asian theropod looked a bit like a scaled-down Allosaurus (which lived in North America), and was probably most closely related to another Asian carnivore of the late Jurassic period, Sinraptor. Not all paleontologists are convinced that Szechuanosaurus deserves its own genus, since it may yet turn out to be a specimen (or species) of an existing genus of theropod.
