I guess they never managed to invent the necessary technology for upright walking. Remember Huey saying, he couldn't get sahelanthropus to walk upright, the only reason it could do so, was because the psychic kid controlled it rather like a puppet than a machine. So I think it's not implausible, that REX was created in Sahelanthropus's "image", but even then the technology necessary for upright walking was not available - it is very complex and fragile, even today, as we know.
