My point wasn't the "mangas" part at all, and perhaps "goofy" wasn't the
proper word.
When the whole scientific naming concept got started, as I recall, Latin and
Greek were used for naming because they were dead languages and would not
change over time. This would be good for ensuring stability in nomenclature.
With that said, Mongolian and Chinese are definitely not dead languages, and
thus would not be particularly suited for naming taxa, except where place
names are concerned. Though, I suppose this would also be a strike against
"Supersaurus" as a name...
