Note on page 56 that Mallon et al. seem to have found a more 
complete and diagnostic specimen of Ceratops, which is from the same 
formation and state.  This would be a great time to declare it a neotype
 of Ceratops montanus, since they say the holotype's also 
indistinguishable from Albertaceratops and Kosmoceratops (from the 
Oldman and Dinosaur Park Formations, respectively).  Then we'd have a 
well preserved and diagnostic type taxon / specifier.  Alas, their 
wording seems to indicate they're going to name the specimen as a new 
species.  :|

By the way, I noticed this week that Lihoreau et al.
 (2014) have done the right thing for ex-dinosaur Libycosaurus that I 
wish more dinosaur researchers would do.  It turns out the holotype of 
the type species of Libycosaurus is lost and cannot be distinguished 
from the three valid species based on published information.  So they 
just leave the type species as a nomen dubium (as it does belong to the 
clade formed by the other species), but also have three valid species in
 the genus too.  That's what should be done with Diplodocus longus, but 
instead we have an ICZN petition to make D. carnegii the type species.
