Re: [dinosaur] Diplodocus status

[David Marjanovic <david.marjanovic@gmx.at>]

I have only three things to add to this thread:

â The institution where I am currently again an unpaid Visiting Researcher 
ceased to belong to the Humboldt-UniversitÃt some 10 years ago and is no 
longer named after Humboldt. It is now simply "Museum fÃr Naturkunde". To 
distinguish it from the one with the same name in Magdeburg, everyone adds ", 
Berlin". The specimen numbers interestingly start with MB, which I suppose 
stands for "Museum Berlin"; this is followed by .R. (no spaces) for the 
"reptiles" in the vertebrate paleontology collection and then (still no spaces) 
by the number.

â The ICZN clarified a while ago that the London specimen is the type 
specimen of *Archaeopteryx lithographica* and the isolated feather is not.

â If Ceratopsidae, named after its type genus *Ceratops*, is to be divided 
into subfamilies, one of them must be named Ceratopsinae. However, *Ceratops* 
is a nomen dubium, and so is Ceratopsinae â it is not clear if it is 
Chasmosaurinae, Centrosaurinae or perhaps even neither that is a junior synonym 
of Ceratopsinae. This does not seem to be regarded as a problem worth mention 
in the literature; Ceratopsidae is treated as consisting of Chasmosaurinae and 
Centrosaurinae, and *Ceratops* and Ceratopsinae are simply ignored. 
Ceratopsinae is Ceratopsidae indet..
