I agree with Mike T. here. There is a tendency among many authors to
tip-toe around family-level names (-idae, -inae, -oidea, etc), and
instead erect names that are studiously non-Linnaean - such as
Laurasiformes (noted by Mike T.), Lognkosauria, Turiasauria,
Elasmaria, Microraptoria, etc.
In each case, a family-level name would have sufficed. Authors are no
doubt spooked by the prospect of becoming entangled with the ICZN and
its outdated rules on naming family-level taxa. If you do name a
family, you have to frame the definition in such a way that a Linnaean
hierarchy is preserved for eternity (-oidea > -idae > -inae > -ini).
Then again, even this rule is flouted. Albert Prieto-Marquez
consistently puts Saurolophidae inside Hadrosauridae in his hadrosaur
I'm fine with abandoning Linnaean taxonomy. But we don't need to
throw the baby out with the bathwater. I reckon we can continue to
use clades ending in -idae for minor clades, as long as we exercise
care in defining these clades. For example, there are available
family-level names for titanosaurian phylogeny going begging:
Antarctosauridae, Nemegtosauridae, Aeolosauridae, Argyrosauridae, etc.
But because they end in -idae, nobody wants to touch them with a
barge-pole. Almost nobody; I give credit to Tom Holtz for being brave
enough to resurrect some of these names:
