RE: Avian Ancestors, new book on theropods

Besides the Averaptora vs. Avialae mess, Agnolin and Novas also explicitly 
redefine Eumaniraptora as (Passer < Troodon), when it is actually (Deinonychus 
+ Passer) and has been universally agreed to be such since it was named in 
1997.  It all seems so pointless, especially since Eumaniraptora would apply to 
the same taxa in their cladogram under either definition.  Why bother having 
phylogenetic nomenclature if you're just going to redefine names?
