Each and everyone of these (except maybe Iliosuchidae) had an existence in
the formal literature independant of phylogenetic taxonomy.

Defining, no.  *COINING*, yes.  Priority, yes.  Form of name, yes.
Synonymy, yes.  There ARE family group rules in the ICZN!  (Not as many as
for species and genera, but they are there).

> and it doesn't cover higher taxa.

True.  BUT just because there is no formal international body governing
these rules doesn't mean there aren't well accepted traditions.  Like having
to have the name published in the text, not just a figure.  And like not
using a name from an undergraduate college-level handout (which is precisely
what Enigmosauria is: a construct by Mike Keesey in my HONR 259C (then 159C)
honors seminar.  Had I not posted it to the list, nor Mike, no one would
have ever heard of it).

A coining (if nothing else) in a peer reviewed papers are still, in the mind
of most researchers, a minimum necessity for any formal taxonomic name in
any system.  Enigmosauria doesn't get that, yet.  (And Darren admits that
the inclusion in the figure is a mistake).

Sure there is!  Don't forget, the Phylocode only governs phylogenetic
taxonomy.  There are still plenty of folks out there who use older taxonomic
systems, so we don't want to go mucking things up and confusing them ahead
of time...
