Overlooked 2002 paper
For those interested in pre-K/T inferred dinosaur ecomorphologies, this paper provides one with interesting deductions from ongoing processes among extant taxa. Taking their paradigms, and using other tools available in the literature, one cannot help but reject the obsequious idea that larger individuals of ornately frilled ceratopsians (the "styracosaurs") were male. In all probability, their social group compositions were female dominant.
