Dingus and Lowe, in "The Mistaken Extinction: dinosaur evolution and the
origin of birds" (New York, NY: W.H. Freeman, 1998) argue that modern
birds have evolved from at least 20 taxa that survived the K/T - this
proposal is based on a combination of direct and indirect evidence.
Unfortunately without the book to hand I cannot give the details. I too
would be interested to know what others think of their reasoning, and
whether any subsequent finds have supported or undermined it.
