[dinosaur] Nomen dubium and nomen vanum

[Thomas Richard Holtz <tholtz@umd.edu>]

I refer the recent discussants on this topic to the following paper, and the references therein:

1. Alvaro MonesÂ(1989)ÂNomen dubium vs. nomen vanum,ÂJournal of Vertebrate Paleontology,Â9:2,232-234,ÂDOI:Â10.1080/02724634.1989.10011757

This discussesÂthe history of these terms, and the ICZN'sÂadoption of the term nomen dubium in 1948 and in the subsequent three editions of the Code.
