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."

    Porcupines are prickly.

    Consider porcupine mating. Very carefully.

    Male: Don't worry dear, you might get poked, but it's just a small prick.
    Mating partner: Yes, I know dear.
