New species of multi-horned dinosaurs unearthed in Utah
Date:9/23/2010

has ensued about the function of the ceratopsian horns and frills of these prehistoric monsters--from fighting off predators to recognizing other members of the same species or controlling body temperature--the dominant idea today is that these features functioned first and foremost to enhance reproductive success. Scott Sampson, first author on the paper, explains, "Most of these bizarre features would have made lousy weapons to fend off predators. It's far more likely that they were used to intimidate or do battle with rivals of the same sex, as well as to attract individuals of the opposite sex."
