If, as the paper seems to imply, turtles are the sister group of crocs among
extant reptiles, and since archosaurs are all the descendants of the common
ancestor of crocs and birds--which would be more distant than the common
ancestor of crocs and turtles--then turtles would be archosaurs. Who knows?
Maybe turtles are derived aetosaurians--lotsa armor plate there, anyway.
