RE: Juravenator; or How not to perform a phylogenetic analysis
And the answer to the question is:
"He'd make a plan, and he'd follow through.
THAT'S what Brian Boitano'd do!"
"For Borsti I'll be a cladist too,
Cause that's what Brian Boitano'd do!"
(Yes, Allen, I am singing this - I promise!) :-o
Anyways, back to the paper... The Supplementary Information shows just how
fragile a monophyletic Compsognathidae is. This has come up previously,
even before the description of _Juravenator_. Good thing that
Compsognathidae was defined as stem-based, with _Passer_ as the external
specifier (Holtz et al., 2004). If the Compsognathidae is shown to be
paraphyletic, it would mean that we have a gaggle of short-armed theropods
near the base of the Coelurosauria, close to the origin of Maniraptora.
Interestingly, the topology shown in the Suppl. Info. would make
Maniraptoriformes a synonym of Coelurosauria. At least using the latest
(Sereno's) definitions, which are faithful to Gauthier's and Holtz's
