Centrosaurinae.  They also move the Ceratopidae down to the node joining all
three :-P instead of ={Chasmosaurus + Centrosaurus} like everyone else has
it (Jon Wagner I am sure is already pulling out his hair).


Two questions-
1. Are they allowed to redefine Ceratopsidae like this?  I know phylogenetic
taxonomy is new and higher taxa aren't covered by the ICZN, but will all you
professionals have to use this definition of the family until/unless someone
else redefines it?
2. Where do they think Zuniceratops and Turanoceratops belong compared to
Avaceratops?
