DESCRIPTION:The ceratopsians\, or horned dinosaurs\, were a diverse group 
 of herbivorous dinosaurs from the Northern hemisphere of the second half o
 f the Mesozoic. They range from animals of just a few kilos up to 8 ton gi
 ants like Triceratops and are famous for their incredible diversity of hor
 ns\, spikes and bosses on both their faces and on the extended frill at th
 e back of the skull. The functions of these have been debated at considera
 ble length in the scientific literature with both inter- and intra-specifi
 c combat\, and species recognition all considered. However\, recently the 
 idea that these were under sexual selection\, previous incorrectly rejecte
 d\, has gained considerable weight. Here it is shown how we can interpret 
 the behaviour and signalling behaviour of these long extinct fossil animal
 s.
