Well, not really. This is all:
'The poem was in all probability written between 133â€"116 B.C.3
...
3 Ginsinger, RE III A, 674.'
where
'RE = Realencyclopadie der classischen Altertumswissenschaft, Stuttgart 1894 ff.'
http://tech.groups.yahoo.com/group/cybalist/message/67478
which means the arguments should be found there.
*****GK: I did find an argumented German text online, but neglected to keep the reference... Unfortunately the RE article is not yet ready for electronic inspection. But the article on Bastarnae is. Here's the reference for interest's sake:
One argument re Ps/Skymnos is that it repeatedly states that it takes its information about the geography of the eastern Black Sea area from Demetrius of Callatis (I think Mullenhof mentions this point), whose work is dated as very late 3rd c. BCE. Of course the counter argument is that Ps/Sk is multi-layered and the "arrivals" note could have been a later postscript.
