Homo sapiens is a mass noun and as such technically does not have a plural form, like "bread," "furniture," or "water."

Presumably Tyrannosaurus rex should be considered as such too, in which case the alleged plural form should, as you suggested, be considered improper slang, and as such shouldn't be noted on the article as an actual plural form, which I'm fine with, though again, I think the article should be considered for deletion regardless.
