(I think someone posted that site on DU, but I can't remember who)

it's in a branch with the sandgrouse, which I haven't heard of, fairly closely related to doves, then flamingos and grebes (their common ancestor was 73.8 million years ago, before the asteroid), and you have go to all the way back to 113.3 million years ago to get to the most recent common ancestor of all living birds ,with ratites like the ostrich the most remote sidebranch.

Sadly, that only shows living species, so you don't see where the birds that didn't make it past the Cretaceous fit in - or other dinosaurs. Next stop going back is the crocodiles.
