With respect to nomina nuda published in 1997, it should be noted that Paul Sereno was going to describe Microcephale when the publisher left out Microcephale the last minute due to limitations of space. Someday, Microcephale may be published as a new genus and species when Sereno has the paper on Microcephale accepted by the publisher and knowledge of pachycephalosaur ontogeny improves (Sereno may be heartbroken if Microcephale proves to be a juvenile of an already known Canadian pachycephalosaur). Moreover, Robert Bakker hasn't published any papers on Morrison theropods lately, so it's doubtful whether "Wyomingraptor" and "Beelemodon" will ever be described as new or sunk into known Morrison genera. Therefore, it may be better to set up a new section for nomina nuda. 126.96.36.199 (talk) 00:42, 2 January 2013 (UTC)Vahe Demirjian
