Relation of crocodiles walked on two legs

This "news" is a bit late, but if you missed it, it's pretty cool: http://tinyurl.com/2nter9

This was a Triassic archosaur found in the same area as all those Coelophysis fossils at Ghost Ranch.  Very interesting.  The article suggests that this two-legged, croc-like animal went extinct, allowing dinosaurs that filled the niche to evolve.  It was a winning design, so why did it go extinct, allowing for the evolution of dinosaurs that were very similar (Struthiomimus, Gallimimus, etc.)?
