Re: Pickering's nomina nuda (was RE: Rob Gay's print-on-demand publication of Kayentavenator elysiae

I find it somewhat ironic that names in a dissertation which have gone through the peer review of a committee and a copy of which can be obtained either by purchase or sometimes free from either Dissertations International or the degree awarding institution are not considered published in an acceptable publication. but those self published through Lulu Press are.

I tend to regard nomina nuda as validly published nomenclature that do not otherwise satisfy the ICZN's requirements for publication as nomina valida. That is, were *Quetzalcoatlus northropi* published without a concurrent description or photo, but in a legitimate venue, it would be a nomen nudum. The same cannot be said of Pickering's taxa, since the ICZN specifically indicates that the lack of satisfaction for two of its requirements means that names he produced aren't even recognized nomina of any sort. While both Mortimer and Olshevsky regard these taxa as nomina nuda, I don't regard them as nomina at all. And not to rag on Mortimer and Olshevsky too much, but there are names that are effectively _nicknames_ of specimens that are used as nomina nuda, and the latter even argues for dissertation-produced names for being nomina, nuda or otherwise, despite the ICZN restricting dissertations from the list of acceptable publications.
  So there are really three levels to this:

  1. Published terminology that roughly corresponds to a label for something, 
be it a clade or a specimen, used as taxonomy. These are not nomina of any sort.

  2. Published terminology that meets some but not all of the ICZN's 
requirements. These are nomina nuda or nomina vana, depending on the usage.

  3. Published terminology that meets all of the ICZN's requirements. These are 
nomina valida (unless set aside for formal reasons -- rejecta -- or forgotten 
through disuse or disregard -- oblita).

  A fourth category, should we feel inclined, lies between 1 and 2 (call it 
1.5) which corresponds to _lapsus calami_, and are not considered nomina nuda 
or anything, and cannot compete for priority or be useful for elevation of 
status, without special action in cases where two names are potential lapses 
for one another.

As noted by Tim, Pickering's works are produced in a
fashion that prohibits access to them, a clear violation of
two of the ICZN's requirements for publication
(accessibility, and deposition), and by this reason are
regarded by the majority (if not all but a very small
number) of workers.
I really didn't think that *anyone* accepts Pickering's proposed new genera ("Walkersaurus") and 
species ("Elaphrosaurus philtippetensis", "Tyrannosaurus stanwinstonorum", etc) as valid. 
Even George Olshevsky, who has erected several dinosaurs names via self-publication, regards Pickering's 
names as nomina nuda (e.g., see http://www.polychora.com/dinolist.html).

Pickering's self-published 'works' typically take the form of paranoid rants 
that cover a wide range of topics, from national socialism to Sigmund Freud to 
King King; the new dinosaur names are inserted as a kind of afterthought. 
However, neither the deplorable and self-indulgent quality of his works, nor 
the fact that the works were self-published, are the reasons why Pickering's 
names are universally held to be nomina nuda. As Jaime says, it is because 
Pickering made no attempt to establish a permanent scientific record. It 
appears that his 'works' (newsletters) were sent unsolicited to various 
paleontologists (and others, such as Steven Spielberg), and therefore qualify 
only as private correspondence.

Thus, when Roger Benson erected the new genus _Duriavenator_ for _Megalosaurus hesperis_, the fact 
that Pickering had previously named the same species "Walkersaurus" had no impact at all 
on priority, because "Walkersaurus" was a nomen nudum.

Nevertheless, it is a frightening thought that if Pickering had bothered to deposit his 
'works', and made them accessible, that we might have been stuck with all his horrible 
monikers ("Elaphrosaurus philtippetensis", and so on). Then again, the more 
likely outcome is that subsequent workers would have ignored his plethora of names in 
their own publications - w
o have happened anyway.
