Story-wise I'd take a guess that whatever happens to Sahalanthropus after the cut mission 51, and probably after the game's story overall, leaves Darpa at least somewhat aware of its existense and basic design. Enough to inspire the REX design, possibly, but not enough to learn about its upright-standing technologies.
