Sexual dimorphism in dinosaurs refers to the different physical characteristics of male and female dinosaurs of the same species.

Findings revealed the caudal chevrons of male crocodiles, used to anchor the penis muscles, were significantly larger than those of females. Methodology/Principal Findings. Here, we reassess potential sexual dimorphism in skulls of Protoceratops andrewsi by applying two-dimensional geometric morphometrics to 29 skulls in lateral and dorsal redoakpta.compal Component Analyses and nonparametric MANOVAs recover no clear separation between hypothetical “males” and “females” within the overall morphospace.

Sexual dimorphism is the condition where the two sexes of the same species exhibit different characteristics beyond the differences in their sexual organs.
