That sister group relationship comes through strongly on the phylogentic tree
in their Nature paper.
There also should be a story of mine up at Newscientist.com, but at the moment
the web site isn't responding. An error message suggests it may be busy.
This is definitely a neat critter, and they've got nearly 2000 bones, which
they can put together to get over 90% of the animal. They also have age
sequences. Kirkland thinks it was a mass death site at a spring. Virtually all
of the bones are Falcarius.
