AW: paleonet question marks in taxonomic names

[Günter Schweigert <schweigert.smns@xxxxxxxxxxxxxxxxxxxxxx>]

Bjoern,

the open nomenclature is not covered by the Codes!
You may have a look in:
Bengtson P., 1988. Open nomenclature. Paleontology 31(1): 223-227.
But therein not all cases are discussed.

The common usage is as follows:
? before a genus name: uncertain occurrence of this taxon.
? after genus name: uncertain affiliation to this genus
? in combination with a species name: uncertain affiliation to this species.

Cheers,
Guenter

Betreff: paleonet question marks in taxonomic names

Dear colleagues,

when the status of a taxon, or the taxonomic position of a specimen  
is not clear in some taxonomic papers the taxa contain question marks  
at different positions, such as:

?Michelinoceras michelini (Barrande, 1866)
Michelinoceras? michelini (Barrande, 1866)
Michelinoceras ?michelini (Barrande, 1866)
Michelinoceras michelini? (Barrande, 1866)

I guess, every position has a different meaning and the position is  
regulated by a rule of the ICZN.
However, where can I find this rule and where is written what the the  
meaning of each specific position of the question mark is?

Any information is appreciated

Bjoern
