Triceratops may have had horns to attract mates
Dinosaurs like the Triceratops may have had horns and frills to attract a mate, a new study suggests.
Ceratopsian, or horned dinosaurs, were previously thought to have developed this ornamentation to distinguish between different species.
This has now been ruled out in a study published in a Royal Society journal.
Instead, the aggressive-looking armour may actually have evolved to signal an animal's suitability as a partner, known as socio-sexual selection.
"Individuals are advertising their quality or genetic make-up," explained Andrew Knapp, lead author of the research reported in Proceedings of the Royal Society B.
"We see that in peacocks too, with their tail feathers."

Peacock: Look at this sign of excess resources! I am a good mate!
Ceratopsian: Look! I'm horny!
